School Drop Out

Abstrak. Penduduk Sulawesi Selatan pada kelompok pengeluaran terendah menunjukkan bahwa banyak dari mereka mengalami putus sekolah. Salah satu faktor yang mempengaruhi angka putus sekolah yaitu lokasi antar wilayah. Tujuan penelitian ini adalah untuk mengaplikasikan regresi spasial untuk memodelkan angka putus sekolah di Provinsi Sulawesi Selatan. Pengujian dependensi spasial dan pemilihan model regresi spasial dilakukan menggunakan uji Moran’s I dan Langrange Multiplier (LM). Dari hasil penelitian, kasus putus sekolah untuk tingkat SMP tidak memiliki dependensi spasial baik dalam lag maupun error dan berdasarkan model regresi klasiknya diperoleh variabel prediktor yang signifikan mempengaruhi variabel respon adalah jumlah penduduk miskin . Sedangkan untuk kasus angka putus sekolah tingkat SMA, diperoleh dependensi spasial dalam error sehingga model regresi spasial yang digunakan adalah Spatial Error Model (SEM) dan matriks pembobotnya adalah queen contiguity. Matriks pembobot tersebut menggambarkan ukuran kedekatan antar wilayah pengamatan. Hasil analisis spasial menunjukkan bahwa variabel prediktor yang signifikan mempengaruhi variabel respon adalah jumlah penduduk miskin  dan kepadatan penduduk , dengan nilai  89,78% dan AIC =  430,604.Kata Kunci: Langrange Multiplier, Moran’s I, Putus Sekolah, Regresi Spasial, Spatial Error Model (SEM).  Abstract. The population of South Sulawesi in the lowest expenditure group shows that many of them have dropped out of school. One of the factors that influence the drop out rate is location between regions. The purpose of this study was applying spatial regression to the model drop out rates in South Sulawesi Province. Spatial dependency test and spatial regression model selection were performed using Moran's I and Langrange Multiplier (LM) tests. From the results of the study, the drop out case for junior high school didn’t have spatial dependencies either in lag or error and based on the classical regression model obtained predictor variable significantly affect the response variable was the number of poor people . As for the case of high school drop out rate, obtained spatial dependency in error so that spatial regression model used was Spatial Error Model (SEM) and weighting matrix was queen contiguity. The weighted matrix represents the measure of proximity between observation areas. The result of spatial analysis indicates that the significant predictor variable influencing the response variable was the number of the poor  and the population density , with  = 89.78% and AIC = 430,604.Keywords: Lagrange Multiplier, Moran's I, School Drop Out, Spatial Regression, Spatial Error Model (SEM).

Resumen: el objetivo es identificar un patrón de aglomeración en la división espacial del empleo en el sector servicios entre los municipios de la región centro de México. Con el método de la econometría espacial, se estimó un modelo de error espacial para el sector terciario. Según los resultados, la elasticidad ingreso del empleo es baja, el peso de las unidades económicas es importante y hay poca sensibilidad al incremento en las remuneraciones. A pesar de que el análisis exploratorio, a partir de Índice de Moran, sugiere efectos de autocorrelación espacial del empleo en la región de estudio, esto no se puede confirmar con suficiente robustez a partir de los resultados de la estimación de un modelo de error espacial. Aunque esta técnica no es novedosa, en México hay pocos trabajos aplicados al empleo en el sector terciario. El parámetro autorregresivo espacial del término de error l aporta evidencia de que existe una asociación espacial local del empleo, más que una global. Se concluye que en el sector terciario, la vecindad espacial entre los municipios de mayor dinamismo ha generado más crecimiento y aglomeración, que en el resto de ellos.Palabras clave: división espacial del empleo; sector terciario de México; autocorrelación espacial (I de Moran); análisis económico espacial; modelo de error espacial; región centro de México.Employment in the tertiary sector. A spatial estimation for municipalities in Mexico’s central region, 1999-2009Abstract: the aim is to identify an agglomeration pattern in the services sector’s spatial division of employment among municipalities in Mexico’s central region. By using the method of spatial econometrics, a spatial error model was estimated for the tertiary sector. According to results, the income elasticity of employment is low, the weight of economic unities is significant and there is little sensitivity to an increase in wages. Although the exploratory analysis, based on Moran’s I, suggests effects of spatial autocorrelation of employment in the region studied, this cannot be confirmed with enough certainty from the results of the estimation of a spatial error model. Despite this estimation technique is not new, in Mexico there are few studies dealing with employment in the tertiary sector. The spatial autoregressive parameter of the error term provides evidence that there is a local rather than global spatial association of employment. It therefore follows that in the tertiary sector spatial vicinity among the most dynamic municipalities has generated more growth and agglomeration than in the rest of them.Key words: spatial division of labor; Mexico’s tertiary sector; spatial autocorrelation (Moran’s I); spatial economic analysis; spatial error model; Mexico’s central region.

Abstract Objective: Cardio-vascular Diseases (CVDs) are a leading cause of death and disease burden across the world, and the burden is only expected to increase as the population ages. The objective of this paper is to explore the patterns of CVD risk factors among women in the late reproductive ages (35-49 years) across 640 districts in India, and investigate the association between area-level socioeconomic factors and CVD risk patterns., using a nationally representative sample of 239,729 women aged 35–49 years from all 36 States/UTs under NFHS-4 (2015–16). Methods: Age-standardized prevalence of CVDs have been calculated, along with 95% CI among women in their late reproductive ages (35–49 years) in India. The spatial dependence and clustering of CVD burden has been examined by Moran's I indices, bivariate Local Indicator of Spatial Autocorrelation (LISA) cluster and significance maps. Ordinary Least Square (OLS) regression has been employed with CVD prevalence as the outcome variable. To consider for spatial dependence, Spatial Autoregressive (SAR) models have been fitted to the data. Diagnostic tests for spatial dependence have also been carried out to identify the best fit model. Results: Higher values of Moran's I imply high spatial autocorrelation in CVD among districts of India. Smoking, alcohol consumption, hailing from a Scheduled Caste background, more than 10 years of schooling, as well as urban places of residence appeared as significant correlates of CVD prevalence in the country. The spatial error model and the spatial lag model are a marked improvement over the OLS model; among the two, the spatial error model emerging to be the most improved of the lot. Conclusions: A broader course of policy action relating to social determinants can be a particularly effective way of CVD risk addressal. Social policy interventions related to health like reduction in inequalities in factors like education, poverty, unemployment, access to health-promoting physical or built-environments are crucial in tackling the long-term effects of CVD inequalities between geographical areas.

This paper examined the effect of socio-economic and environmental factors on obesity in Cleveland (Ohio) using an OLS model and three spatial regression models: spatial error model, spatial lag model, and a spatial error model with a spatially lagged response (SEMSLR). Comparative assessment of the models showed that the SEMSLR and the spatial error models were the best models. The spatial effect from the various spatial regression models was statistically significant, indicating an essential spatial interaction among neighboring geographic units and the need to account for spatial dependency in obesity research. The authors also found a statistically significant positive association between the percentage of families below poverty, Black population, and SNAP recipient with obesity rate. The percentage of college-educated had a statistically significant negative association with the obesity rate. The study shows that health outcomes such as obesity are not randomly distributed but are more clustered in deprived and marginalized neighborhoods.

The Impact

The aim of this paper is to conduct a spatial correlation study of virus transmission in the Hubei province, China. The number of confirmed COVID-19 cases released by the National Health and Construction Commission, the traffic flow data provided by Baidu migration, and the current situation of Wuhan intercity traffic were collected. The Moran’s I test shows that there is a positive spatial correlation between the 17 cities in the Hubei province. The result of Moran’s I test also shows that four different policies to restrict inter-city traffic can be issued for the four types of cities. The ordinary least squares regression, spatial lag model, spatial error model, and spatial lag error model were built. Based on the analysis of the spatial lag error model, whose goodness of fit is the highest among the four models, it can be concluded that the speed of COVID-19 spread within a certain region is not only related to the current infection itself but also associated with the scale of the infection in the surrounding area. Thus, the spill-over effect of the COVID-19 is also presented. This paper bridges inter-city traffic and spatial economics, provides a theoretical contribution, and verifies the necessity of a lockdown from an empirical point of view.

The Relationship

This study aims to analyze poverty using spatial models. The researchers also compared the Spatial Error Model (SEM) and Geographically Weighted Regression (GWR). The comparison of the two models was based on the estimation evaluation criteria and the constructed spatial associations. Spatial regression is considered very appropriate to be used to model the relationship pattern between poverty and explanatory variables when the observed data has a spatial effect caused by the proximity between the observation areas. The spatial dependence of errors on observational data can be overcome using SEM, while the effect of heterogeneity of spatial variance can overcome using GWR.

Life Expectancy At Birth

The Human Development Index (HDI) is a human development index that is used to achieve the development outcomes of a region. HDI is formed by 3 basic dimensions, namely the health dimension as seen from the indicator of life expectancy at birth, the dimension of knowledge seen from a combination of indicators of average length of schooling and expectation of school years and dimensions of decent living standards as seen from the indicator of average per capita expenditure has been adjusted. The development of HDI in Central Java shows an increase every year. In 2018 the HDI figure for Central Java Province reached 71.12% and increased by 0.6% from the previous year. This is because the large HDI figures in an area are influenced by the large HDI numbers in adjacent areas. The location / area factor is thought to have a spatial dependence effect on the HDI figure. This problem can be overcome by using spatial regression by including the relationship between regions into the model. The spatial regression approach used in this study is the Spatial Error Model (SEM). The weighting matrix used in this study is Queen Contiguity (intersection between sides and corners). This study provides results that the variables that significantly influence HDI are poverty and school enrollment rates.

Spatial Autoregressive

The regression model that can be used to model spatial data is Spatial Autoregressive (SAR) model. The level of accuracy of the estimated parameters of the SAR model can be improved, especially to provide better results and can reduce the error rate by resampling method. Resampling is done by adding noise (noise) to the data using Ensemble Learning (EL) with multiplicative noise. The research objective is to estimate the parameters of the SAR model using EL with multiplicative noise. In this research was also applied a spatial regression model of the ensemble non-hybrid multiplicative noise which has a lognormal distribution of cases on poverty data in East Java in 2016. The results showed that the estimated value of the non-hybrid spatial ensemble spatial regression model with multiplicative noise with a lognormal distribution was obtained from the average parameter estimation of 10 Spatial Error Model (SEM) resulting from resampling. The multiplicative noise used is generated from lognormal distributions with an average of one and a standard deviation of 0.433. The Root Mean Squared Error (RMSE) value generated by the non-hybrid spatial ensemble regression model with multiplicative noise with a lognormal distribution is 22.99.

The Impact

It is noteworthy that there is a substantial literature review that examines the impact of transportation infrastructure on urban and regional economic performance. It is observed that such infrastructure investments are focused on the economic growth as well as the spillover effect in applied studies carried out in this respect. In this study, in which the effects of highway transportation infrastructure on urban output and the spillover effect of these investments are determined using the spatial econometric method, 81 cities in Turkey have been taken into consideration, and according to the results of the study, transportation infrastructure investments in Turkey have been found to contribute positively to urban output. Also, while the Moran's I test statistic reveals the spatial dependence of such investments, the Lagrange multiplier test results also determine the need to use the spatial error model. The spatial error model results reveal the existence of the positive spillover effect of transportation infrastructure investments.
