Just found another useful site and textbook. Stephen A. Sweet, and Karen Grace-Martin Stephen (http://faculty.ithaca.edu/ssweet/ ) is Associate Professor, Sociology, Ithaca College specialising in Work, Family and the Life Course. Karen (http://www.theanalysisfactor.com/about/about-karen-grace-martin/ ) runs her own consultancy The Analysis Factor (http://theanalysisinstitute.com/) on which there are dozens of entries for statistics, including 61 posts under SPSS alone (http://www.theanalysisfactor.com/category/statistical-software/spss/). She offers occasional free webinars (http://www.theanalysisfactor.com/webinars/) and you can sign up for future ones and download recordings of previous ones (http://www.theanalysisfactor.com/webinars/recordings/) but these may be a bit advanced for beginners. Specific postings include SPSS, SAS, R, Stata, JMP? Choosing a Statistical Software Package or Two. http://www.theanalysisfactor.com/choosing-statistical-software/ and I'm waiting for a review copy of the book, but looking at the publisher's blurb, checking out entries on Karen’s own site and seeing her profile, I think I've found another kindred spirit. Although it's basically a statistics textbook, it uses data from the General Social Survey and is probably more appropriate for social science students than Andy Field's book.

I am trying to run a two stage least squared regression (2sls) in SPSS. While it is available under Analayze....Regression......2sls.... I am not clear how to do the following; 1. How do I test the suspected variables for endogenity? Literature tells me about the Wu-Hausman F test and the Durbin-Wu-Hausman chi-sq tests- can these tests be run in SPSS?? 2. How do I check, in SPSS, whether the instrument variables that I have used are “Weak” or “Strong”? 3. Also when I run the 2 sls I have the option to save the values for “Predicted” and “Residuals” as New Variables – from the Options box in SPSS. Can I use these to test for the weakness /strength of the instrument variables? My queries are specific to SPSS only…. I am aware that the above questions can be handled in E Views or STATA but would like to do these in SPSS….. to teach to my class who have access to SPSS only.
