Structural Equation Modeling

I updated the multi-group models section because some people asked how I did the model comparisons.

I've finished the markdown files. Some folks also requested the analyses with the free public

I had a request to convert the svg files in the Markdown files to png so people can use them in

I've finished the rest of the markdown files for the book. It makes a bit more sense to put them

Well, folks, this one was a bit exhausting, but at least it has cool pictures: http://rpubs.com/

Hi Phil, This looks awesome. Thanks for sharing! --Mary On Fri, Aug 8, 2025 at 12:32 PM Phil Wood

I have a few spots left for my fully live and online Latent Class/Profile Analysis workshop using

A series of live-streamed online one-day quantitative methods training courses to be held online in

Actually you can do quite a few things with it, it turns out. FWIW https://youtu.be/WNg4dYY98XU

Here's another video showing how to compare nested models, how to rename parameters, how to move

I updated the video to get rid of some dead space at the end of the video (I'm still learning!)

Basically, this talksa bout how to use onyx to draw a path diagram, using single regression models as

People come into my classes on SEM with a variety of levels of expertise and preferred software

There were some questions as to how to do IRT and calculate the difficulties and discriminations in

I drew together my comments on this (categorical dependent variables include such things as likert-

Featuring longitudinal invariance models, identification of longitudinal invariance when factors are

I posted a talk about multi-group SEM's. This covers Amos (which hasn't changed much) as well

Hi folks, In class I gave a demo on the math you need for generating simulated data for a power study

Some of you might prefer to work with Amos rather than Mplus, lavaan, or Onyx. I made a short video

Dear Nicky, This is obviously something that I think about rather a bit. The basic idea that one time

These are some adapted examples from the Mplus website (I changed some of the analyses to Bayesian
