WebKS Statistics measures whether model is able to distinguish between prospects and non-prospects. Two ways to measure KS Statistic Method 1 : Decile Method This method is … In statistics, the Kolmogorov–Smirnov test (K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2), one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution (one-sample K–S … Meer weergeven The empirical distribution function Fn for n independent and identically distributed (i.i.d.) ordered observations Xi is defined as The … Meer weergeven The Kolmogorov–Smirnov test may also be used to test whether two underlying one-dimensional probability distributions differ. In this case, the Kolmogorov–Smirnov statistic is where Meer weergeven A distribution-free multivariate Kolmogorov–Smirnov goodness of fit test has been proposed by Justel, Peña and Zamar (1997). The test uses a statistic which is … Meer weergeven • Lepage test • Cucconi test • Kuiper's test • Shapiro–Wilk test • Anderson–Darling test • Cramér–von Mises test Meer weergeven The Kolmogorov distribution is the distribution of the random variable $${\displaystyle K=\sup _{t\in [0,1]} B(t) }$$ where B(t) is the Brownian bridge. The cumulative distribution function of K is given by Meer weergeven While the Kolmogorov–Smirnov test is usually used to test whether a given F(x) is the underlying probability distribution of Fn(x), the procedure may be inverted to give confidence limits on F(x) itself. If one chooses a critical value of the test statistic Dα such that … Meer weergeven The Kolmogorov–Smirnov test is implemented in many software programs. Most of these implement both the one and two sampled test. • Meer weergeven

WebIf y is numeric, a two-sample (Smirnov) test of the null hypothesis that x and y were drawn from the same continuous distribution is performed. Alternatively, y can be a character string naming a continuous (cumulative) distribution function, or such a function. In this case, a one-sample (Kolmogorov) test is carried out of the null that the ... WebFigure 1 – Two-sample Kolmogorov-Smirnov test. We carry out the analysis on the right side of Figure 1.
