Examine Standardized Loadings
You have created and summarized the text-speed model in previous steps using the HolzingerSwineford1939
dataset. You were able to view the coefficients for the model using the summary()
function. However, the unstandardized coefficients in the Estimate
column are often hard to interpret for how well they represent the latent variable.
In this exercise, add the standardized = TRUE
argument to your summary()
function to view the standardized loadings. Look at the Std.all
column for the completely standardized solution to see which variables have a poor relationship to the text speed latent variable.

# Load the lavaan library
library(lavaan)
# Load the data and define model
data(HolzingerSwineford1939)
text.model <- 'textspeed =~ x4 + x5 + x6 + x7 + x8 + x9'
# Analyze the model with cfa()
text.fit <- cfa(model = text.model, data = HolzingerSwineford1939)
# Summarize the model
