Abstract: gformula is an implementation of the g-computation procedure, used to estimate the causal effect of time-varying exposure(s) (A) on an outcome (Y) in the presence of time-varying confounders (L) that are themselves also affected by the exposure(s). The procedure can also be used to address the related problem of estimating controlled direct effects and natural direct/indirect effects when the causal effect of the exposure(s) on an outcome is mediated by intermediate variables, and in particular when confounders of the mediator-outcome relationships are themselves affected by the exposure(s).
