Abstract

The volatilities of time series data often experience heteroscedastic problems. Heteroscedasticity is a nuisance variable in the regression equation having a variance that is not constant. Therefore, methods to analyze the problem of heteroscedasticity are needed. This study aims to demonstrate how to eliminate the problem of heteroscedasticity. The method used is, GoldFeld-Quandt. As for eliminating the problem of heteroscedasticity by assuming the variance of interference variables proportional to E(Yi)2
