LSTM models enhance causal inference estimator for complex sequential data

Researchers have developed a new plug-in estimator for the g-formula, a method used to estimate causal effects of sustained treatments, particularly in scenarios with treatment-confounder feedback. This novel approach utilizes long short-term memory (LSTM) models, which are adept at handling complex temporal dependencies in sequential data, as an alternative to traditional parametric models. Initial findings suggest that the LSTM-based estimator demonstrates reduced bias and achieves near-nominal confidence interval coverage in complex data generation mechanisms, such as those found in HIV cohorts, compared to parametric methods.
