Compare adaptive interventions in a SMART with a binary, longitudinal outcome

About This Code

This code is used to estimate and compare change in the log-odds of success in a binary longitudinal outcome for the adaptive interventions embedded in a SMART.

How can a behavioral scientist use this code?

Behavioral intervention scientists can use this code to make inferences about the relative causal effects of one adaptive intevention versus another using data from a SMART with a longitudinal binary outcome.

What method does this code implement?

This code implements a weighted least squares regression approach that is similar to longitudinal regression analyses using GEE with a logit link. In a SMART, the weights (which are potentially impacted by treatment) are known, by design.
