Regional frequency analysis of extreme rainfalls in the west coast of Peninsular Malaysia using partial l-moments

This study was to reinstate the development of regional frequency analysis using L-moments approach. The Partial L-moments (PL-moments) method was employed and a new relationship for homogeneity analysis is developed. For this study, the PL-moments for generalized logistic (GLO), generalized pareto...
