Dataset (Simple Mediation Model, Two Groups)

Generated from a simple mediation model, n = 200, two groups, n = 100 each.

Usage

simple_med_mg

Format

A data frame with 500 rows and four variables:

gp

gp, the grouping variable

x

x, the independent variable

m

m, the mediator

y

y, the dependent variable

Details

This model is used for examples like this one:

library(lavaan)
mod <- "m ~ x
        y ~ m"
fit <- sem(mod, simple_med_mg, gp = "group")
summary(fit)

Examples

print(head(simple_med_mg), digits = 3)
#>    gp      x      m     y
#> 1 gp1 -0.345   7.28 -5.64
#> 2 gp1 -0.366  -5.45 -4.53
