Convenient Approach

Simple and multiple linear regression analyses are statistical methods used to investigate the link between activity/property of active compounds and the structural chemical features. One assumption of the linear regression is that the errors follow a normal distribution. This paper introduced a new approach to solving the simple linear regression in which no assumptions about the distribution of the errors are made. The proposed approach maximizes the probability of observing the event according to the random error. The use of the proposed approach is illustrated in ten classes of compounds with different activities or properties. The proposed method proved reliable and was showed to fit properly the observed data compared to the convenient approach of normal distribution of the errors.

The Mean

The goal of this research is to compare multiple linear regression coefficient estimations with multicollinearity. In order to quantify the effectiveness of estimations by the mean of average mean square error, the ordinary least squares technique (OLS), modified ridge regression method (MRR), and generalized Liu-Kejian method (LKM) are compared (AMSE). For this study, the simulation scenarios are 3 and 5 independent variables with zero mean normally distributed random error of variance 1, 5, and 10, three correlation coefficient levels; i.e., low (0.2), medium (0.5), and high (0.8) are determined for independent variables, and all combinations are performed with sample sizes 15, 55, and 95 by Monte Carlo simulation technique for 1,000 times in total. As the sample size rose, the AMSE decreased. The MRR and LKM both outperformed the LSM. At random error of variance 10, the MRR is the most suitable for all circumstances.

The purpose of this research was conducted to know the influence of: (1) Simultaneous Non Performing Loan and Loan to Deposit Ratio against Return On Asset, (2) Partial Non-Performing Loan against Return On Asset and (3) partial Loan to Deposit against Return On Asset Corporate Banking the Go Public period 2010 – 2012.The research uses quantitative research plans. The research subject is a banking company that go public from 2014 – 2016 and the objects are Non Performing Loan, Loan to Deposit Ratio and Return On Asset.Data collected using documentation methods and analyzed with multiple linear regression analyses. The results showed that (1) Non Performing Loan and Loan to Deposit Ratio simultaneously had significant effect on Return On Asset.(2) Non Performing Loan partially negative effect on Return On Asset, (3) Loan to Deposit Ratio positively affects the Return On Asset of the banking company listed on the Indonesia Stock Exchange.The value of the coefficient of determination (adjusted R2) of 0.323 or 32.3%, this translates to 32.3% of ROA variations that can be explained by variations of independent variables of the NPL and LDR.The remaining 67.7% is explained by other reasons outside of the regression model.Based on the results of multiple linear regression analyses indicating that the NPL has a significant negative impact on ROA, LDR has a significant and positive effect on Roa, NPL and LDR.

This study aims to examine and obtain empirical evidence about the effect of capital intensity, executive character, and sales growth on tax avoidance in Indonesia public listed consumer goods industry companies over the period of 2016-2018. Using a purposive sampling method, the sample selected in this study is 30 companies. This study uses multiple linear regression analyses to examine the effect of independent variables on the dependent variable. This study shows that capital intensity and executive characteristics have significant effects on tax avoidance. Meanwhile, sales growth has no significant effect on tax avoidance.

The aim of the current study is to investigate whether 6-year-old children’s temperament predict their level of attachment. The study has a descriptive design. During the Spring term of the academic year 2017-2018, 59 children (60-72-month old) and their mothers in City of Tekirdağ (Süleymanpaşa District) volunteered to participate in the study. Demographics Form, Incomplete Stories with Doll Family and Short Temperament Scale for Children were used for the data collection. Descriptive statistics were performed to summarize the ISDF and STSC scores in the first step of the data analysis. A multiple linear regression was carried out and attachment scores and temperament sub-dimension scores were assigned as the dependent and independent variables, respectively. Multiple linear regression analyses revealed that the independent variables in the model predicted 16% of the dependent variable (R2 = .157), which meant that the children’s temperament predicted 16% of their attachment levels. Reactivity, sociability, rhythmicity and the linear combination of children’s reactivity, persistence, sociability and rhythmicity did not predict children’s attachment, but persistence did.

ANALISIS VARIABEL YANG BERPENGARUH TERHADAP KINERJA PERUSAHAAN DI BURSA EFEK INDONESIAOleh : Suseno STIE SATRIA Purwokerto ABSTRACT The aims of the research are (1) to analyze influence of age, scale, financial leverage, and profitability to performance of firms at The Indonesian Stock Exchange. (2) to determine the most influential variable on the performance of the firms. Hypotheses proposed in this research were: (1) Age, Scales, Financial Leverage, Profitability influences the performance of firms, (2) Age influences the performance of firms, (3) Scales influences the performance of firms, (4) Financial Leverage influences the performance of firms, (5) Profitability influences the performance of firms. Instrument of analysis employed in the research was multiple linear regression with t test and F test.The results of analyses of t test showed that profitability did not influence the performance of the firms. It was indicated by the value of computed t which was smaller than the value of t table. Meanwhile, the t test of age, scale and financial leverage indicated that the value of computed t > t table. It means that these variables (scale and financial leverage) influenced the performance of the firms. The F test showed that the independent variables of age, scale, financial leverage and profitability as a whole significantly influenced the performance of the firms. It was indicated by the calculated F > the value of F table, the value the age computed t which was smaller than the value of -t table..Based on the research results that age and profitability do not influence the performance of the firms, it is suggested that investors should not pay any attention to those variables. On the other hand, they should pay attention to the variables of scale and financial leverage. It is recommended that for further research should include longer periode of the sample.
