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.
