Kizzy,
I don't know of an online HLM tutorial for SPSS, but would caution you against using HLM in SPSS. I have done HLM analyses in recent past first with SPSS and then with HLM 6 softwre. The results are different. This difference is not minor either, you will draw different conclusions (opposite in my case) from the results of each software. I do prefer HLM 6 and believe it to be the one that gives correct answers. There are a couple of books that deal with HLM in SPSS specifically. One is Leech, Barrett, and Morgan's SPSS for Intermediate statistics. The other is of course Norusis' SPSS 16.0 advanced statistical procedures companion. Of the two I much prefer Norusis' book.

To All, especially to the publishers of SPSS,
On a related note: Would it not be quite helpful and not all that complicated to expand the SPSS Aggregate function to compute regression components? It seems to me that if Aggregate included Intercept and Regression Coefficient functions it would be possible to do rough and ready, but easy to control and examine, hierarchical modeling based on the products of Aggregate runs. (By the way, Aggregate gets my vote as the most useful recent addition to SPSS functionality.)

Why not use SPLIT FILES and OMS with sav format for this? That would work with (almost) any SPSS procedure to give you a dataset of resuilts for each split?

(Grin) AGGREGATE is immensely useful; I've posted more solutions using AGGREGATE than I'd care to count. AGGREGATE is a main reason SPSS works so well with files with 'long' data organization, usually more easily than those with 'wide' organization. But it's not a recent addition. It's been in SPSS at least since release 6 for the mainframe (NOT SPSS 6 for Windows!), in 1975. AGGREGATE came into its own when MATCH FILES was added, in SPSSX [release 1] for mainframe and Vax, c. 1983. And it's had excellent extensions since: MODE=ADDVARIABLES; MEDIAN as an aggregation function; the current highly efficient implementation that does not require the data be sorted. ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.

The alogroithms used in various HLM packages differ somewhat so some
variation in results is to be expected. That is certainly true of MIXED and HLM. But you must also ensure that your code specified analyses that were truly identical. I ran a test of SPSS MIXED and HLM some time ago and came up with nearly identical results (to several decimal places) for that particular data set. Most of my analyses, however, involve binary outcomes - unfortunately SPSS MIXED cannot handle binary outcomes.

I would recommend Gwilym Pryce's Heteroscedasticity Testing and Correcting in SPSS. You can find it on Raynald's web site:

It may also be worth considering that there are some problems which look like heteroscedasticity but which have a more fundamental reason. One is the inappropriate choice of method for a variable which is inherently non-normal. When events are counted the result is inevitably non-normal (because counts are whole numbers rather than continuous and can't be negative for a start). Such variables which have variances which are (roughly) equal to their mean values follow the "Poisson distribution" and SPSS has routines specifically designed for such variables. In my experience it is common to have variances which increase more rapidly than the means, a problem known in the trade as "over-dispersion". Some Poisson distributions (but certainly not all of them) can be fixed by analysing the square root of the dependent variable. ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.
