Analisis Regresi Robust pada Pengukuran Kinerja (Studi Kasus Perumahan Martubung Medan)

Abstract

Robust regression analysis in measuring housing environmental performance can provide significant benefits. This method can help identify and overcome uncer- tainty in measurement results, so that decisions regarding environmental pro- tection and management can be made more accurately. This type of research is quantitative with a descriptive approach. Population of 1567 in 12 blocks in Martubung Simple Type Housing, with a total sample of 144 randomly select- ed residents involved in the research process. The data analysis technique us- es robust regression analysis. The results of this research show that the results of robust estimation regression estimates-M on the environmental performance of simple housing, obtained a robust regression equation estimation-M, namely ˆy = 15.562 + 0.476X1 − 0.453X2 + 0.222X3 − 0.427X4. Based on the results of the p-value test, it shows that Population Attributes, House Attributes, Ener- gy Consumption Volume and Utilities and Services have a significant effect on environmental performance. The results of the hypothesis test of the M-estimate robust regression method on the environmental performance of simple housing showed that the population attribute and energy consumption volume variables had a positive and significant influence on environmental performance, while for the house attribute variable and utilities and services had a negative and signifi- cant influence on environmental performance.
