Hello,
I am using Stata 15.0 and have developed a logistic model which I would like to internally validate on my training dataset and obtain the c-statistic, brier scaled, e:o ratio, calibration in the large and calibration slope. The package "bsvalidation" seems to be exactly what I need but alas, it doesn't seem to run on Stata 15.0 and despite transferring the installed package files from 17.0 (which I cannot access the dataset with for various reasons) I get the error message "this is version 15.0 of Stata; it cannot run version 16.0 programs".
Any advice on how I can achieve the above in Stata 15.0? I have never run a bootstrap internal validation in Stata before so was hoping I could rely on a package to do it for me as I wouldn't be able to write the code myself.
Many thanks in advance
