COMMA: COrrecting Misclassified Mediation Analysis

COMMA provides a set of functions for the analysis of mediation models with binary mediator misclassification.

The two main parts are:

• Classification probability calculations
• Parameter estimation

The package allows users to compute the probability of the latent true mediators and the conditional probability of observing a mediator value given the latent true mediator, based on parameters estimated from the COMMA_EM, COMMA_PVW, and COMMA_OLS functions.

Jointly estimate parameters from the true mediator, observed mediator, and outcome mechanisms, respectively, in a mediation analysis with a binary misclassified mediator variable. Three methods are provided for parameter estimation: an ordinary least squares correction procedure, a predictive value weighting approach, and an expectation-maximization algorithm.
