Construction of Dependence Structure for Rainfall Stations by Joining Time Series Models with Copula Method

Copula model has applied in various hydrologic studies, however, most analyses conducted does not considering the non-stationary conditions that may exist time series. To investigate dependence structure between two rainfall stations at Johor Bahru, methods have been applied. The first method considers condition exists data, while second assumes stationarity series data. Through goodness-off-fit (GOF) and simulation tests, performance of both are compared this study. results obtained study highlight importance non-stationarity hydrological
