Applications of the propensity score weighting method in psychogeriatric research: correcting selection bias and adjusting for confounders

Abstract

The propensity score (PS) weighting method is an analytic technique that has been applied in multiple fields for a number of purposes. Here, we discuss two common applications, which are (1) to correct for selection bias and (2) to adjust for confounding variables when estimating the effect of an exposure variable on the outcome of interest.
