sobelTest_one: Sobel test for the indirect effect - Single mediator path

Description

This function takes the parameter estimates and covariances and performs the Sobel test for one mediator, or a single mediator path for multiple unordered mediators.

Usage

sobelTest_one(
  mu1,
  sig1,
  mu2,
  sig2,
  sig12,
  indL = 1,
  mu3 = 0L,
  sig3 = 0L,
  sig13 = 0L,
  sig23 = 0L,
  mu1_0 = 0,
  mu2_0 = 0,
  mu3_0 = 0
)

Value

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

Arguments

mu1: Value of the estimate of the independent variable on the mediator.
sig1: Value of the variance of the estimate of the independent variable on the mediator.
mu2: Value of the estimate of the mediator on the response.
sig2: Value of the variance of the estimate of the mediator on the response.
sig12: Value of the covariance between mu1 and mu2.
indL: Value indicating the value of the independent variable used for the interaction. Typically 1.
mu3: Value of the estimate of the effect of the interaction of the independent and mediator variable on the response.
sig3: Value of the variance of the estimate of the effect of the interaction of the independent and mediator variable on the response.
sig13: Value of the covariance between mu1 and mu3.
sig23: Value of the covariance between mu2 and mu3.
mu1_0: Null value for mu1.
mu2_0: Null value for mu2.
mu3_0: Null value for mu3.
