Currently, NCL does not have a Kolmogorov-Smirnov Test (KST).

As noted in Numerical Recipes( NR): The accepted test for differences
between binned distributions is the chi-square test. For continuous
data as a dunction of a single variable, the mos generally
accepted test is the Kolmogorov-Smirnov Test.

We can not include the NR codes for the KST
due to copyright reasons. However, if you have
the book you can use the codes as a shared object.

We will look into including a KST in a future release.


For the record, NCL does have some chi-square related functions:

cdfchi_p, cdfchi_x:
