st: Bootstrapping metan for odds ratios
I have noticed that when attempting to bootstrap the metan (version 1.86) user command with the "or" odds ratio option the following error message is returned.
option or not allowed r(198);
This does not happen for either the "rr" or "rd" metan options whose returned statistics can be bootstrapped. The bootstrap command appears to interpret the "or" as a logical or operator (which can be denoted by |).
To bootstrap metan with the "or" option I have placed it within a program.
program callmetan metan cases_treated notcase_treated cases_control notcase_control, /// label(namevar=id) randomi nograph or end
It is then possible to use the program with the bootstrap command.
bootstrap ES=r(ES) tau2=r(tau2), reps(100): callmetan
Thanks to Dr. Alex Sutton for assistance with this problem.
