Hi,
I am using midas to create a forest plot in Stata/MP 13.1 with the following command:

midas TP FP FN TN, id(Author Year) ms(0.75) ford fors bfor(dss)

but I keep getting an error message that indicates 'Variable tp not found', I am not sure why this is happening as I was able to run metandi just fine (stata code: metandi TP FP FN TN, plot).
Any suggestions would be much appreciated. Thank you in advance.

Rowena
