In saccosj/modarea:

Description

Moderation Area is used to quantify the effect size of interactions in moderated multiple regression. It calculates the area between simple slopes lines at set low and high SDs, and standardizes the value given theoretical space.

Usage

modarea(x, y, m, xSD, mSD, K)

Arguments

x	predictor
y	outcome
m	moderator
xSD	low and high SDs of the predictor to test
mSD	low and high SDs of the moderator to test
K	number of bootstrap iterations

Examples

x1 = rnorm(1000,0,1)
m1 = rnorm(1000,0,1)
e1 = rnorm(1000,0,1)
y1 = x1 + m1 + x1*m1 + e1

modarea(x1, y1, m1, 1, 1, 10000)
