Hace 5 días · Common statistical tests include the Kolmogorov-Smirnov test, Anderson-Darling test, and Chi-square goodness-of-fit test, which compare the observed data with the expected distribution. Graphical methods, such as Q-Q plots and P-P plots, visually assess how well the data aligns with the theoretical distribution.

10 de may. de 2024 · The Tests of Normality table contains two different hypothesis tests of normality: Kolmogorov-Smirnov and Shapiro-Wilk. Kolmogorov-Smirnov (K-S) is a nonparametric test. It technically can be used to test if the data come from a known, specific distribution (not just the normal distribution).
