Distribution of Two Samples (Population)

[P_S_]

Hi Everyone,

I need a statistical test to show that the distribution of two samples are the same.

I was thinking I could probably test to see if both the distributions are normal or not but then it necessarily does not have to be a normal distribution and these could be any other distribution. So this might not work for my case.

Is there a way i could test that the distibutions are the same. Any code/examples will be very helpful.

Thank you,

PS.

Look at proc npar1way.

SAS/STAT(R) 9.2 User's Guide, Second Edition

[JacobSimonsen]

The Kolmogorov Smirnov test whether the two distribution-functions are the same in a nonparametric way.

this can be done with PROC NPAR1WAY with the KS-option. It also gives some some other test for the same hypothesis, but the Kolmogorov-Smirnov test are the most well-know.

Or test if their percentiles is equal or not .
