However, the exact formula for front-door adjustment depends on the structure of the graph, which is difficult to learn in practice.

The meta model seeks to answer "what would the outcome be if we were to deploy a different

The proposed implementation of Gunsilius' algorithm computes For example, in the expenditure dataset (see Section I.3), In Figure 4, we show the results of Gunsilius's algorithm for three different Note that this algorithm works on the empirical CDFs of all variables, i.e., they are all scaled to lie Figure 4: We show results of Gunsilius's algorithm for 3 different settings of The practical issue of course is the optimization. That alone is already very computationally demanding and has convergence problems. A practical resource, sample size, limits the representational size of the estimator. How to achieve "enough variability" without aiming at a completely flexible distribution of In any case, the finite mixture of Gaussians approach can still be implemented with the reparameter-ization trick. The relation to Gunsilius algorithm is that our "base measure" is smoothly adaptive, leading to possibly more stable behavior in practice.

Local treatment effects are a common quantity found throughout the empirical sciences that measure the treatment effect among those who comply with what they are assigned. Most of the literature is focused on estimating the average of such quantity, which is called the " local average treatment effect (LATE) " [
