why is ks non parametric what test is used to compare normally distributed data why use a ks test which is an example of a parametric test for data analysis? why use k-s test why use ks to test the distribution why use k-s test is kolmogorov-smirnov parametric which parametric test is used to compare error distributions between two sets of data what is k-s test why ks test is used versus parametric test? why do researchers use the kolmogorov smirnov test what is k-s data why do not use k-s test what type of test is k s why use k-s test for data analysis why use k-s test when to use k-s test what type of test to use to compare normal distributions and normal error distributions what is the purpose of the ks test for comparing the distribution of data
