how to add confounding variable

billi — Mon, 06 Jan 2020 18:01:06 GMT

I am working with a multi level data. Data is attached.

In this dataset, I have 8- X variable: cumulative risk (continuous), all other risk (dichotomous).

3- Y variables: insurance and practice (dichotomous) and time (continuous)

I have one confounding variable Age (continuous).

I will have to add random effect to X variable. But I am confused how to add confounding variable to this analysis. Can anybody please show me how to do that? Also, can this analysis be done in JMP if add random effect?

Thanks in advance
