In this paper, a Monte Carlo study is performed to determine the validity of using the root mean square error as a selection criterion for the frequency analysis. This statistic is compared to those from the Kolmogorov- Smirnov, the Cramer-Von Mises and the Anderson-Darling tests. The distributions chosen to compare these statistics are gamma, Weibull, Gumbel, log-normal and log-logistic. The results obtained by this study indicate that at least 50 random observations are needed to obtain good results using either the Anderson-Darling or root mean square error statistics. The Kolmogorov-Smirnov and Cramer-Von Mises tests are not recommended since they require sample sizes larger than those usually found in hydrology.
