Mediation Indirect Effect Variance Calculator

Compute the variance of an indirect effect in a mediation model using Sobel's multivariate delta method, given the regression coefficient and standard error for the relationship between the mediator and the dependent variable, and the regression coefficient and standard error for the relationship between the independent variable and the mediator. Knowing the variance of an indirect effect can be very useful in analytics studies that rely on mediation models.
