cliff's Delta effect size in SAS

Is there a proc for calculating cliff's D in SAS?

 

I used proc glm to compute treatment effect b/n 3 groups : control, OA and LSS.  the glm procedure with effectsize option gives the partial omega square value as below:

ω partial 2 = [SS – DF x MSE] / [SS + (N – DF) MSE]

Where MSE= Mean square error and N is the number of observations

SS = Sum of squares

 

How is this ω partial 2  measure different from Cliff's D?

 

Thank you.
