Calculator: Variance for an Indirect Mediation Effect
Variance Calculator for an Indirect Mediation Effect
This calculator uses Sobel's multivariate delta method to compute the variance of an indirect effect in a mediation model, given the regression coefficient and standard error for the relationship between the independent variable and the mediator, and the regression coefficient and standard error for the relationship between the mediator and the dependent variable.
