Uji Satu Sampel Kolmogorov Smirnov (One Sample K-S)
himasta.unimus.ac.idUji Kolmogorov-Smirnov merupakan uji yang lebih kuat daripada uji chi-square ketika asumsi-asumsinya terpenuhi. Keunggulan Uji Kolmogorov-Smirnov dibanding Uji Chi Square: 1. Chi Square memerlukan data yang terkelompokkan, kolmogorov smirnov tidak memerlukannya. 2. Uji kolmogorov – smirnov lebih efisien untuk sampel berukuran kecil 3.

The NPAR1WAY Procedure - SAS
support.sas.comPROC NPAR1WAY computes empirical distribution function (EDF) statistics, which test whether the distribution of a variable is the same across different groups. These statistics include the Kolmogorov-Smirnov test, the Cramér–von Mises test, and the Kuiper test. Exact p-values are available for the two-sample Kolmogorov-Smirnov test.

Weibull Analysis
www.statvision.comModified Kolmogorov-Smirnov D Weibull D 0.0901357 Modified Form 0.568059 P-Value >=0.10 Small P-Values (less than 0.05 if operating at the 5% significance level) lead to a rejection of the Weibull distribution. In the current example, the P-Value is large, suggesting that the Weibull distribution is a reasonable model for the data.

internationaljournalofcaringsciences.orgwas tested by using Kolmogorov–Smirnov test. Frequency and percentage were used to express the descriptive statistics of categorical variables. Quantitative data were also expressed in mean and standard deviation (SD) for the variables with normal distributed data and median for non-normally distributed data.
Checking normality in Excel
www.sheffield.ac.ukThe Kolmogorov-Smirnov test and the Shapiro-Wilk’s W test are two specific methods for testing normality of data but these should be used in conjunction with either a histogram or a Q-Q plot as both tests are sensitive to outliers and are influenced by sample size :
Nonparametric statistics and model selection
www.mit.eduThe Kolmogorov-Smirnov test computes the statistic D n: D n = max x jF1 n (x) F2 n (x)j This compares the two CDFs and looks at the point of maximum discrepancy; see Figure5.1 for an example. We can theoretically show that if F1 is the empirical distribution of xand F2 is the true distribution xwas drawn from, then lim
