Isotemporal substitution modeling (ISM) command

[Hui SHI]

Hi,

I have 4 variables and named as: sleep, SB, LPA, MVPA, and depression (outcome).

Have someone familiar with Isotemporal substitution model and tell me which command I should use?

I can not find tutorial materials and code for Isotemporal substitution modeling (ISM).

Thanks very much

Hello Hui SHI

I am in the same situaiton. I guess you may have already fond answers. I have been using the lincom command however I'm considering using margins instead but I'm a bit lost. I wonder if you could help me.
Thank you!
