Mplus programs, 4/16/2009
Given time, we will employ a number of Mplus programs today. First, we will revisit our example
from last time in which we replicated the books illustration. This time, though, we will work in the
correlation metric. Here is the modified version of the
first program
we ran last time, and here is the
second program.
Next, we will investigate two phases of a mimic analysis. First, we will look at our model
without covariates.
Then we will
add a covariate.
We will follow that up with a by-group analysis that is similar conceptually. On our
initial attempt,
we will encounter problems. However, with some recoding, we will implement the
by-groups analysis,
(albeit with some sample-size related issues).
Finally, we will perform a similar analysis on a larger data set. There will be five programs involved:
