I conducted several partial Spearman correlations to test association between two variables while controlling for several variables using a script because SPSS does not provide this option directly.

However, I would also need to report the power analysis for the non-parametric partial Spearman correlations but SPSS does not provide this option i.e. by default the power analysis for partial correlation is for Pearson partial correlation.

Does anyone by any chance know how to do power analysis for nonparametric partial Spearman correlation? Or perhaps if a script could be provided this could be run on SPSS.

Thank you in advance
