sample size calculation (cohen's d)?

[bhr-q]

I want to use an estimated effect size (like Cohen’s d) to do the sample size calculation.

To perform the sample size calculation using a range of effect sizes, for example, 0.2, 0.3, 0.4, 0.5.

Could you please let me know what is the code for that? 

Thanks

I don't think anyone can provide code for you unless you first provide a lot more information about the actual problem. It seems since you are talking about Cohen's D that you are fitting some sort of model to some data. But please explain further the exact problem and the exact model you plan to fit.

In the meantime, please take a look at the PROC GLMPOWER documentation and see if it helps.

I found this way IN TH EGOOGLE USING PROCPOWER
TWOSAMPLEMEANS TEST=DIFF
MEANDIFF = 0.2 0.3 0.4 0.5
STDDEV = 1
POWER = 0.9
NTOTAL = .;
RUN;

sorry, I was in a rush and didn't notice your explanation, Thank you for your answer, and for sure I will go through that and put the comment if face a problem.
