classic teaching data set for Multi-Level Modeling

Does anybody have available either
1) a public data set and syntax that is routinely used in teaching MLM or
2) syntax to produce a set of data to demo MLM for teaching.

If you do, would you please send them to me?

Hi Art. I have the data & syntax for many of the examples in Jos Twisk's nice (and very accessible) introductory book, "Applied Multilevel Analysis: A Practical Guide". I'll send them to you off list.

You can preview parts of Twisk's book at Google Books. It is not as complete as some of the other books that are out there, and probably not as authoritative either. But IMO, it does a much better job than most of presenting the basic concepts in a very understandable fashion. I found that after reading Twisk (and working through his examples), it was much easier to read some of the other books that are out there than it had been 'before Twisk'. ;-)

Cheers,
Bruce

Thank you.
Do you recall whether any of these examples have 3 levels?

Hi Art,

Here's an example that was provided to me a while back. I've changed a few things for ease of interpretation. The code begins by generating the data and ends with fitting the model. Var_Level1 is the indicator variable for level 1 (e.g. student), Var_Level2 is the indicator variable for level 2 (e.g. class), and Var_Level3 is the indicator variable for level 3 (e.g. school). z1 is a level-2 covariate while x1 and x2 are level-1 covariates.

HTH,

Ryan

Re: classic teaching data set for Multi-Level Modeling

In reply to this post by Art Kendall

Hi J. P.,

Which data set are you working with, what version of SPSS are you using, what messages do you get with SPSS, and what results does HLM give (particularly for the covariance parameters for the random effects)? The most common reason for failures of convergence in mixed models in my experience is specification of a model with more covariance parameters than the data will support, resulting in redundant covariance parameters. If you'll provide the information I've requested, I'll be happy to look into this.

I have had a very difficult time getting three level models to converge with SPSS. Works fine with HLM 6.0 but not with SPSS. Maybe there is an error in my syntax. Here it is for a three level longitudinal model: (no missing data)
