I want to do post hoc power analysis for Co regression. I want to calculate power in SAS for cox regression. I can find the hazard ratio and confidence interval from other studies. How can find R square and standard deviation for these code proc power; coxreg hazardratio = 1.4 rsqu...
2 Because post-hoc analyses are typically only calculated on negative trials (p ≥ 0.05), such an analysis will produce a low post-hoc power result, which may be misinterpreted as the trial having inadequate power.As an alternative to post-hoc power, analysis of the width and magnitude of ...
slopes. Now I would like to carry out a posthoc power analysis to see how much power the study has. Is there any light in Stata in relation to this? I have seen Stata's ''power repeated'' command which does not suit here as they are suitable for one/two way repeated ANOVA designs...
