SCM forward inclusion checks
Hello,
I am unable to get in touch with [email protected] in order to
join the network, therefore I am attempting to directly reach out to you,
as I have a question that I would like to post to the nmusers list. I have
written it down below. Thank you,
Kind regards,

Hello nmusers,
I am currently working on automating the checks performed at each step of
the SCM forward inclusion pass. This requires setting up precise
quantitative thresholds. Once a candidate relationship has been identified
to be included in the model based on its LRT p-value, what is your strategy
in order to confirm covariate inclusion before moving to the next forward
inclusion step? Namely:
1. What threshold of omega decrease do you use for the omega on which
the covariate is included? If omegas of other parameters increase or
decrease, does this impact your decision? And if yes, how? (i.e what
threshold do you use?)
2. All other quantitative checks that you might perform on:
- the epsilon or residuals
- the extent of the covariate effect on the PK parameter
- other (please specify)
Thank you very much for your help.
Kind regards,
