Which is more powerful Anderson Darling or Kolmogorov Smirnov?

Which is more powerful Anderson Darling or Kolmogorov Smirnov?

To cut a long story short: Anderson-Darling test is assumed to be more powerful than Kolmogorov-Smirnov test.

How to do the Kolmogorov-Smirnov test for normality?

As for the Kolmogorov-Smirnov test for normality, we reject the null hypothesis (at significance level α) if Dm,n > Dm,n,α where Dm,n,α is the critical value. where c(α) = the inverse of the Kolmogorov distribution at α, which can be calculated in Excel as where KINV is defined in Kolmogorov Distribution.

Which is better Anderson Darling or Cramer von misses?

To sum up, I would recommend you to use Anderson-Darling or eventually Cramer-von Misses test, to get much more powerful test. Each of the three tests have better power against different alternatives; but on the other hand, all three exhibit varying degrees of test bias in some situations.

How to calculate the KINV of the Kolmogorov distribution?

where c(α) = the inverse of the Kolmogorov distribution at α, which can be calculated in Excel as Dm,n,α = KINV (α)*SQRT ((m+n)/ (m*n)) where KINV is defined in Kolmogorov Distribution. The values of c(α) are also the numerators of the last entries in the Kolmogorov-Smirnov Table.

Which is more sensitive Cramer von Mises or Kolmogorov Smirnov?

There’s another test — the Cramér-von Mises test — which looks at the sum of squares of the differences in cdf (at the data). It’s often somewhat more sensitive than the Kolmogorov-Smirnov to the kind of differences we tend to want to pick up (because it can “accumulate” small but consistent differences rather than needing a single large one).

Which is better Anderson Darling or ks test?

However, Anderson Darling test is more sensitive at the tail, thus is better than KS test for fat tailed distributions. But are there any explanations (intuitively or theoretically) for this statement?

What are the critical values of the Anderson Darling test?

The critical values for the Anderson-Darling test are dependent on the specific distribution that is being tested.

How to calculate approximate p value for Anderson Darling?

ADPROB(x, n, dist, k, iter, interp, txt) = an approximate p-value for the Anderson-Darling test at x (which is set to the AD statistic) for the specified distribution, based on an interpolation of the critical values in the table in Anderson-Darling Statistical Table, using iter number of iterations (default = 40) to calculate the approximation.
