Value

A p-value for the test for the indirect effect.

Arguments

sig1: Value of the variance of the estimate of the independent variable on the first mediator.
mu2: Value of the estimate of the first mediator on the second mediator.
sig2: Value of the variance of the estimate of the first mediator on the second mediator.
mu3: Value of the estimate of the second mediator on the response.
sig3: Value of the variance of the estimate of the second mediator on the response.
mu2b: Value of the estimate of the effect of the interaction of the independent and first mediator variable on the second mediator.
sig2b: Value of the variance of the estimate of the effect of the interaction of the independent and first mediator variable on the second mediator.
mu3b: Value of the estimate of the effect of the interaction of the independent and second mediator variable on the response.
sig3b: Value of the variance of the estimate of the effect of the interaction of the independent and second mediator variable on the response.
