Demo.twolevel

Demo dataset for a illustrating a multilevel CFA.

Description

A toy dataset containing measures on 6 items (y1-y6), 3 within-level covariates (x1-x3) and 2 between-level covariates (w1-w2). The data is clustered (200 clusters of size 5, 10, 15 and 20), and the cluster variable is “cluster”.

Usage

data(Demo.twolevel)

Format

A data frame of 2500 observations of 12 variables. clusters.

y1: item 1
y2: item 2
y3: item 3
y4: item 4
y5: item 5
y6: item 6
x1: within-level covariate 1
x2: within-level covariate 2
x3: within-level covariate 3
w1: between-level covariate 1
w2: between-level covariate 2
cluster: cluster variable

Examples

head(Demo.twolevel)

model <- '
    level: 1
        fw =~ y1 + y2 + y3
        fw ~ x1 + x2 + x3
    level: 2
        fb =~ y1 + y2 + y3
        fb ~ w1 + w2
'
fit <- sem(model, data = Demo.twolevel, cluster = "cluster")
summary(fit)
