Abstract

Inequality is a state where there is an imbalance between each other. Inequality indicates the unevenness ofdevelopment that runs in an area. In Central Java, the problem of inequality among people still exists in daily life.Geographically Weight Regression method is a method that yields model parameter estimators that have localizedproperties at each point or location. In this study aims to modeling the inequality problem that occurred in CentralJava using Geographically Weight Regression method that has the nature of localization at the point. Data takenfrom Central Statistics Agency (BPS) 2015. Through Geographically Weight Regression method can beconcluded that with OLS method got 2 variables effect on imbalance wit h α 10% is variable of HDI  (IPM) andPDRB. While the influential GWR method is the number of population and the amount of labor. While goodnessof fit test showed there is no difference between GWR model and OLS model or in other words there is no spatialeffect in the imbalance analysis in Central Java Province (0.4976 <0.1).Keywords: inequality, GWR,Spatial

Abstract

Metode statisika sangat berperan penting dalam memprediksi maupunmenduga. Salah satu metode yang digunakan adalah dengan analisisregresi semiparametrik spline. Bentuk estimator Spline Truncated sangatdipengaruhi oleh nilai titik knots. Oleh karena itu, pemilihan titik knotoptimal mutlak diperlukan. Metode pemilihan titik knot dengan GCV.  Dua algoritma dan pemograman  untuk mendapatkan pemodelan regresisemiparametrik spline truncated dengan menggunakan software R yaitualgoritma dan program untuk menentukan Knot optimal berdasarkan metodeGCV, algoritma dan program untuk mengestimasi model regresisemiparametrik Spline Truncated. Keywords: Spline Truncated, GCV, Software R.
