Se determinó un perfil de la infraestructura de una población rural en Venezuela con respecto a la vivienda según el sector, realizando un análisis de correspondencias simple en donde se compararon las variables de infraestructura con respecto a la variable “sector”.  La base de datos se obtuvo de una investigación previa basada en un cuestionario del censo de población y vivienda del Instituto Nacional de Estadística (INE) de una muestra de 226 hogares. Los resultados obtenidos variaron según el tipo de infraestructura y servicios básicos del sector. La técnica de análisis de correspondencias simple mostró ventajas y desventajas como método para caracterizar poblaciones.   Palabras clave: Análisis de correspondencias simple, análisis multivariante, caracterización, infraestructura.   Abstract A profile of the infrastructure of a rural population in Venezuela was determined with respect to housing according to the sector, performing a simple correspondence analysis in which the infrastructure variables were compared with respect to the variable "sector". The database was obtained from a previous investigation based on a questionnaire of the population and housing census of the National Institute of Statistics (INE) of a sample of 226 households. The results obtained varied according to the type of infrastructure and basic services in the sector. The simple correspondence analysis technique showed advantages and disadvantages as a method to characterize populations.   Keywords: Simple Correspondence Analysis, Multivariate Analysis, Characterization, Infrastructure.

<p><em>Tingkat keparahan CAP adalah poin penting pengambilan keputusan perawatan pasien. Beberapa metode telah digunakan untuk menilai tingkat keparahan pneumonia seperti Pneumonia Severity Index (PSI), CURB-65, SMART-COP dan Expanded CURB-65. Metode tersebut memiliki kelebihan dan kekurangan. Expanded CURB 65 diusulkan menjadi metode yang lebih akurat untuk mengevaluasi keparahan pneumonia dan memprediksi kematian pasien CAP. Tujuan penelitian ini memprediksi keakuratan Expanded CURB  65 dibandingkan CURB 65 dan PSI. Penelitian kohort prospektif pada pasien CAP yang dirawat di RSUP Dr. M.Djamil Padang dari April sampai Oktober 2019. Tingkat keparahan CAP pada pasien dinilai menggunakan PSI, CURB 65, Expanded CURB 65, kemudian hasilnya dievaluasi berdasarkan keparahan. Data dianalisis menggunakan regresi logistik dengan CI 95% dan nilai p &lt;0,05 dianggap signifikan. Hasil penelitian pada 90 pasien sebagian besar laki-laki usia 53 tahun dengan komorbiditas terbanyak keganasan. Uji Pearson Chi aquare menunjukkan tidak ada hubungan antara tingkat keparahan berdasarkan CURB 65 dan luaran pengobatan (CI 95%, nilai p = 0,104). Sementara, PSI dan Expanded CURB 65 memiliki hubungan yang signifikan antara tingkat keparahan dan luaran (CI 95%, p=0,081 dan CI 95%, p= 0,046, masing-masing). Analisis multivariat menemukan Expanded CURB 65 lebih akurat dalam memprediksi luaran pasien CAP rawat inap (kappa =0,108 dan AUC=0,422).</em></p><p><em><br /></em></p><p><em><em>Severity of CAP is very important for site care decision inpatients.

The HJ biplot is a multivariate analysis technique that allows us to represent both individuals and variables in a space of reduced dimensions. To adapt this approach to massive datasets, it is necessary to implement new techniques that are capable of reducing the dimensionality of the data and improving interpretation. Because of this, we propose a modern approach to obtaining the HJ biplot called the elastic net HJ biplot, which applies the elastic net penalty to improve the interpretation of the results. It is a novel algorithm in the sense that it is the first attempt within the biplot family in which regularisation methods are used to obtain modified loadings to optimise the results. As a complement to the proposed method, and to give practical support to it, a package has been developed in the R language called SparseBiplots. This package fills a gap that exists in the context of the HJ biplot through penalized techniques since in addition to the elastic net, it also includes the ridge and lasso to obtain the HJ biplot. To complete the study, a practical comparison is made with the standard HJ biplot and the disjoint biplot, and some results common to these methods are analysed.

En el presente trabajo estimamos un indicador sintético de la actividad económica mensual de la ciudad de San Carlos de Bariloche para el período 2006-2020. A partir de la metodología de diferencias simétricas y un conjunto de series asociadas con el ciclo económico local, se obtiene un indicador que representa la actividad económica de la ciudad. Este refleja el efecto de eventos exógenos sobre la actividad económica local y permite estimar el impacto del COV ID-19. Este trabajo es el primer intento en la elaboración de un indicador para sintetizar la actividad económica de la ciudad y constituye un aporte a las estadísticas locales. Sin embargo, los problemas para disponer de los datos estadísticos oficiales –en concreto, los relevados por la Municipalidad de Bariloche– suponen una limitación significativa para la continua actualización del índice. No obstante, la carencia de la totalidad de datos oficiales se suple con técnicas estadísticas para proyectar el índice general (6 series) a partir de un índice parcial (3 series). Palabras clave: indicadores económicos, ciclos económicos, economías regionales, COV ID-19

The hunting tactics of male and female leopards in the southern Kalahari were analysed for prey-specific patterns. The field study was based on tracking leopard spoor in the sandy substrate of the Kalahari. Visual profiles for each type of prey were compiled for various facets of hunting. Data sets were analysed further, using Correspondence Analysis and Detrended Correspondence Analysis. The results indicate that multivariate analysis can be used to demonstrate prey-specific hunting tactics in Kalahari leopards. In using a scarce prey base, Kalahari leopards seem to be number maximisers as they are unselective of prey type, age or sex. The presence of prey-specific hunting tactics may indicate a move along a continuum towards some degree of energy maximisation.

Correspondence analysis is an exploratory data analysis technique for the graphical display of contingency tables and multivariate categorical data. Its history can be traced back at least 50 years under a variety of names, but it has received little attention in the marketing literature. Correspondence analysis scales the rows and columns of a rectangular data matrix in corresponding units so that each can be displayed graphically in the same low-dimensional space. The authors present the theory behind the method, illustrate its use and interpretation with an example representing soft drink consumption, and discuss its relationship to other approaches that jointly represent the rows and columns of a rectangular data matrix.
