West Kalimantan Province is one of the provinces with the lowest MYS rates in Indonesia, with only one out of its 13 districts/cities fulfilling the compulsory education policy. Therefore, research is needed to obtain the best model and understand the factors that influence the MYS districts/cities of West Kalimantan Province. This study uses the Geographically Weighted Panel Regression (GWPR) analysis method, due to the annual changes in MYS numbers indicating time effects in data and differences in MYS numbers in each district/city indicating differences in characteristics between regions. GWPR is a combination of panel data regression model and geographically weighted regression (GWR) model. The results showed that the best model obtained is the GWPR adaptive bisquare model with an AIC value of-147.241 and R 2 value of 80.07%. The variables of per capita income, dependency ratio, literacy rate, and the number of schools significantly influence MYS, and four groups of regions are formed based on significant variables.

One of the model of spatial regressions is the Geographically Weighted Regression (GWR). In the analysis, the GWR method considers the differences in characteristics between regions (spatial heterogeneity). Diarrhea cases in toddlers can be modeled using the GWR model. This research aims to model and identify factors that significantly influence diarrhea cases in toddlers in each district in East Java Province in 2020 using GWR. There are two weighting functions used in this research that are fixed bisquare kernel and adaptive bisquare kernel. The results showed that the GWR model with the adaptive kernel bisquare weighting function was more suitable because it produced the highest 2 value of 79.29%. The factors that have a significant effect in each district are different and the dominant factor is the provision of vitamin A to toddlers.

Factors that used in this study are the external factors include the proportion of public high/vocational school, proportion of the classrooms high/vocational school have damaged, the proportion of high/vocational school teachers have certified, and the number of participants high/vocational school national examination. This study uses Poisson regression analysis. Poisson regression is included in the Generalized Linear Models and this is one of the regression analysis for count data models with Poisson distributed response variables. Poisson regression analysis methods assume the mean and variance of the response variables are equal. Response variable is said to be Poisson distributed and overdispersion not happen if the value of the ratio between the variance and the mean close to one and less than 2.5. Test results show the response variable in this study Poisson distributed and there is no overdispersion. The analysis showed that all four factors are independent variables in this study affect the response variable is the number of high school/vocational school students which do not pass the examination.

Income inequality in Indonesia is measured by an indicator named Gini Ratio. BPS Indonesia noted that in March 2021, the Gini Ratio in Indonesia was 0,384. This figure shows that Indonesia belongs to the category of moderate income inequality, which means that income in Indonesia is not well distributed or there is an inequality in income distribution. For this reason, the inequality that occurs needs to be decreased by recognizing the factors that affect it. The purpose of this study was to determine the factors that significantly affect the Indonesia's Gini Ratio in 2016-2020 by applying panel data regression. The results show that the model chosen to represent the Indonesia's Gini Ratio in 2016-2020 is a fixed time effect model with 2 of 40,282%, which is significantly be affected by the human development index, population, open unemployment rate, percentage of poor people, and average hourly wage for worker.
