A Study on Error of Frequence Rainfall Estimates Using Random Variate

In the study rainfall frequency analysis attempted the many specific property data record duration it is differance from occur to error-term and probability distribution of concern manifest. Error-term analysis of method are fact sample data using method in other hand it is not appear to be fault that sample data of number to be small random variates. Therefore, day-rainfall data to randomicity consider of this sample data to the Monte Carlo method by randomize after data recode duration of form was choice method which compared an assumed maternal distribution from splitting frequency analysis consequence. In the conclusion, frequency analysis of chuncheon region rainfall appeared small RMSE to the Gamma Ⅱ distribution. In the rainfall frequency analysis estimate RMSE using random variates great transform, RMSE is appear that return period increasing little by little RMSE increased and data number increasing to RMSE decreasing.
