Hi,
I am trying to calculate the detectable alternative for a dichotomous outcome expressed as a relative risk given my sample size and a power of 0.90;
Is there a command/package in STATA that does this? [i saw that this can be calculated for Cox proportions]
The sampsi command only allows calculation of power or sample size as far as I can tell;
Thank you,
Elliott
