In [[statistics]], the '''Kolmogorov–Smirnov test''' ('''K–S test''' or '''KS test''') is a [[nonparametric statistics|nonparametric test]] of the equality of continuous (or discontinuous, see [[#Discrete and mixed null distribution|Section 2.2]]), one-dimensional [[probability distribution]]s that can be used to compare a [[random sample|sample]] with a reference probability distribution (one-sample K–S test), or to compare two samples (two-sample K–S test). It is named after [[Andrey Kolmogorov]] and [[Nikolai Smirnov (mathematician)|Nikolai Smirnov]]. | In [[statistics]], the '''Kolmogorov–Smirnov test''' ('''K–S test''' or '''KS test''') is a [[nonparametric statistics|nonparametric test]] of the equality of continuous (or discontinuous, see [[#Discrete and mixed null distribution|Section 2.2]]), one-dimensional [[probability distribution]]s that can be used to compare a [[random sample|sample]] with a reference probability distribution (one-sample K–S test), or to compare two samples (two-sample K–S test).
