Dear Statalist, 

I would be grateful if you could help me on a problem:

Having submitted an article to a Journal, the reviewers asked me for power calculation on a Spearman’s rank correlation coefficient.

This happened although I had been very careful with the interpretation of negative findings in the manuscript. Moreover, Spearman’s rank correlation coefficient was the appropriate choice for the univariate analysis performed, due to a variety of underlying factors.

To my knowledge, there is no command through which STATA can perform power calculations on Spearman’s rank correlation coefficients.

Please inform me if there is a way to overcome this difficulty. Are there any commands I am not familiar with? Would programming STATA be of value? 

What would be the optimal approach to this issue? The need for power calculations in Spearman's rank correlation coefficients seems justified.

I thank you in advance.

T.S.
University of Athens, Greece
