2-sample Kuiper Test Function: performs Kuiper Test for two sets samples of observations
Description
2-sample Kuiper Test Function: performs Kuiper Test for two sets samples of observations
Usage
kuiper.2samp(x, y)
Arguments
x |
an array of sample observations |
y |
the other array of sample observations |
Value
Kuiper test statistic and p-value
Note
The computation of the p-value takes references from Paltani(2004) which states that the functions (in the set of four formulas) never underestimates the false positive probability however it can be a bit high when the sample size in the range of 40 to 50 a factor of 1.5 is quoted at the 1e-7 level
