asq_ord_bool: Is the mediation effect significant?

In ieTest: Indirect Effects Testing Methods in Mediation Analysis

Is the mediation effect significant?

Description

This function takes 3 U values for the asq-test for 2 ordered mediators, as well as an alpha level. It returns whether the test would reject at the given alpha level. Additionally, the cutoff, either specified by number of squares or the percentage towards the center of the transformation region, can be specified. This function is primarily called by the asq_ord function to determine if the test is significant at one of a chosen set of alpha values.

Usage

asq_ord_bool(alpha, u1, u2, u3, numSquares = 4L, upLim = 0.5)

Arguments

alpha	Significance level for the test.
u1, u2, u3	The U values to be used in the test
numSquares	The number of squares to be used in the asq-test. Always superceded by upLim
upLim	The allowed extension, between 0 and 1, of the squares towards the center of the region

Value

A boolean variable indicating if the indirect effect null hypothesis is rejected.

Examples

asq_ord_bool(.05, .02, .015, .995, upLim = .75)
