Abstract
Analisis regresi merupakan salah satu analisis untuk menentukan tingkat pengaruh suatu variabel independen dan variabel dependen. Masalah utama dari metode ini adalah jika metode ini diterapkan pada data spasial. Untuk mengatasi permasalahan pada data spasial, maka metode statistik yang akan digunakan adalah Geographically Weighted Regression (GWR), yaitu model yang mengakomodasi faktor geografis sebagai variabel independen yang dapat mempengaruhi variabel dependen. Penentuan parameter dan pemodelan GWR dalam penelitian ini menggunakan software R 2.9.0. Penelitian ini bertujuan menganalisis faktor-faktor yang mempengaruhi debit puncak di sub DAS (Daerah Aliran Sungai) Lesti. Metode yang digunakan untuk menganalisis adalah model regresi OLS (Ordinary Least Square) dan GWR. Hasil penelitian menunjukkan bahwa faktor geografis tidak berpengaruh secara signifikan terhadap model GWR, atau tidak ada perbedaan antara model regresi OLS dengan model GWR.

Regression analysis is one of the analyses used to determine the level of influence of an independent variable on a dependent variable. The main problem with this method occurs when it is applied to spatial data. To overcome problems with spatial data, the statistical method used is Geographically Weighted Regression (GWR), which is a model that incorporates geographical factors as independent variables that can influence the dependent variable. Parameter estimation and GWR modeling in this research were performed using R 2.9.0 software. This research aims to analyze the factors influencing peak discharge in the Lesti sub-watershed (DAS). The methods applied for the analysis are the OLS (Ordinary Least Squares) regression model and GWR. The results indicate that geographical factors do not have a significant effect on the GWR model, or that there is no difference between the OLS regression model and the GWR model.
