WebWe will now run the KS test to compare two samples, both from normal distribution, to each other. from scipy.stats import ks_2samp s1 = np.random.normal (loc = loc1, scale = 1.0, size = size) s2 = np.random.normal (loc = loc2, scale = 1.0, size = size) (ks_stat, p_value) = ks_2samp (data1 = s1, data2 = s2) WebKolmogorov-Smirnov test是一个有用的非参数（nonparmetric）假设检验，主要是用来检验一组样本是否来自于某个概率分布（one-sample K-S test），或者比较两组样本的分布是否相同（two-sample K-S test）。 先介绍一下one-sample K-S test，two-sample K-S test类似。 假设我们有观测值X1， X2，。 。 。 ，Xn，我们认为这些值来自某个分布P …

Web2 aug. 2014 · If you were to use the KS test assuming known parameter values, the critical values of the test statistic tend to a constant multiple of the correct ones as sample size increases, e.g. for a 5% significance level it's 78% of what it should be. So doing it wrong is very conservative. (Lilliefors discusses this in the paper.) Aug 2, 2014 at 9:32 Web16 mrt. 2024 · The 2 sample Kolmogorov–Smirnov test of distribution for two different samples.

It is a nonparametric test (appropriate for datasets which are not normally distributed).
