Propensity score matching assigns a propensity for group assignment, which is then used to create 2 groups that are balanced across all possible variables that might influence exposure assignment. When used in the proper conditions, these analytics allow for more accurate and precise estimates of ...

confounding variables is kept in proportion across all values of the exposure variable. The balancing weights from propensity score matching or inverse propensity score weighting do not always sufficiently balance the confounding variables, so their weighted correlations are calculated compared to ...
