Works of A. N. Kolmogorov and N. V. Smirnov devoted to one-sided and t
wo-sided criteria of concordance and uniformity are considered. It is
shown that the use of the term ''Kolmogorov-Smirnov criterion'' is not
correct. Recommendations on the use of the terms ''Kolmogorov criteri
on,'' ''Smirnov criterion,'' and ''Kolmogorov-Smirnov criterion'' are
given.
