Psm neighbor
Webas propensity-score matching (PSM). PSM does not need bias correction, because PSM matches on a single continuous covariate. In contrast, the nearest-neighbor matching … WebThis study introduces a new PSM algorithm, referred to as iterative matching, that may improve upon the nearest neighbor with caliper approach and is easier to implement than optimal matching. In the new approach, treatment-control pairs are selected iteratively, with only the mutual best matches selected in each iteration.

WebDec 11, 2013 · PSM (propensity score matching) is widely used to reduce bias in non-randomized and observational studies [1], [2], [3]. The propensity score (PS), introduced by Rosenbaum and Rubin in 1983 [4], is defined as a subject's probability of receiving a specific treatment conditional on a group of observed covariates.
