V. B. Bagdonavicius, M. S. Nikulin

Abstract


In this communication we consider chi-squared goodness-of-fit tests from censored data. Choice of random grouping intervals as data functions is considered. Simple formulas useful for computing of test statistics for mostly applied classes of survival distributions are given.
