What are the similarities between the Marginal Structural model and the structural nested means model?
Marginal structural models
are a class of statistical models used for causal inference in epidemiology. Such models handle the issue of time-dependent confounding in evaluation of the efficacy of interventions by inverse probability weighting for receipt of treatment....
The structural nested means model---
They isolate the average effects of treatment at each time interval as a function of moderators available prior to that time interval. ...
Hence both are dependent on time or time interval...this is the most common similarity between them....
Note-if there is any understanding problem regarding this please feel free to ask via comment box..thank you
