Double-robust estimation in longitudinal data with time-varying confounding: a simulation study

This is a repository of code related to the work-in-progress above, nicknamed "drsim."

Three programs are provided under drsim/code:

1. drsim_ltmle.R : Generates simulations and analyzes data using Longitudinal Targeted Minimum Loss-Based Estimation (LTMLE).
2. drsim_ipw.R : Generates simulations and analyzes data using inverse probability weighting (IPW).
3. drsim_truth.R : Generates 2 large simulations, identical except that in the first exposure is set to 1 and in the second exposure is set to 0, and obtains the true risk differences.

We further provide the following files under drsim/results:

1. drsim_truth.txt : The output of drsim_truth.R, a file containing the true risk difference by maximum number of time points included.
