ABSTRACT
In different fields of environmental research statistical distributions, especially beta distribution, can be used. The purpose of this paper is to compare different goodness-of-fit tests and their power in modeling an environmental parameter, namely the relative humidity. The concrete values of this parameter that have been taken into account are the ones recorded in Ramnicu Valcea, Romania, during July 2010. Four goodness-of-fit tests were dealt with, in order to find out which of them is the most appropriate in describing the relative humidity. Only one of these tests (Cramér-von Mises, Anderson-Darling, Watson and Kolmogorov-Smirnov) seems to fit with the experimental data, and this is the Anderson-Darling test.
