Permutation Based Paired Kolmogorov-Smirnov Test
Description
Permutation Based Paired Kolmogorov-Smirnov Test
Usage
colppks(x, y, R = 999)
Arguments
| x | A numerical matrix with data. | 
| y | A numerical matrix with data. | 
| R | The number of permutations to perform. | 
Details
The permutation based Kolmogorov-Smirnov test for paired samples (Wang W.S., Amsler C. and Schmidt, P., 2025) is performed. The x and y matrices contain the paired observations. The i-th column of x is paired with the i-th column of y.
Value
A vector with permutation based p-values. Each p-value corresponds to a column in the matrices.
