Hi all.
I have a cross-sectional dataset with 190 participants (95 parent-child pairs). I have data that indicates who the pairs are, and their relationship within the pair. I am conducting logistic regression analyses and my co-author indicates that I need to perform a correlated logistic regression and/or specify an exchange correlation structure. This is all SAS-speak and I am having difficulty translating this to appropriate SPSS syntax. Several colleagues have indicated that I need to use GEE but my understanding of GEE is that it requires repeated measures data, which is not what I have. Does anyone have any suggestions? Be advised I am not a statistician or epidemiologist, so you'll need to use verbage akin to "SPSS for dummies". Thanks in advance. |

What I would suggest is constructing a new dataset, in which each case
represents all the parent variables plus (with different names) all the child variables. Then, an ordinary logistic regression can be run with some predictors referring to the parent and some to the child. I suppose the dependent variable is some state or event occurring to the pair, or to the child, and this event or state can be predicted by characteristics of the parent and characteristics of the child. For instance, school success might be predicted by child's age and parent's age, by parent's education and child's nutritional status, and so on. Apart from the above, you may also want to run the same logistic regression (separately) on the parent dataset and on the children data set, perhaps to see whether the same predictors are significant or whatever. Other than that, I do not know of any procedure called "correlated logistic regression".

I suspect your co-author means "conditional" logistic regression. SPSS has no canned procedure for that, but it can be obtained via the COXREG procedure. Marta García-Granero posted a nice example to this list a few months ago--you should be able to find it in the archives at: http://www.listserv.uga.edu/archives/spssx-l.html

It sounds like you do have repeated measures.
Repeats are not just based on times. members of a couple would be
repeats. Parent/child would be repeats. The same variable measured
under different conditions. Split plots are repeats, as are twins,
litter mates, left/right eye, pairs of almost anything, etc.
Some dialectics of statistics (e.g., SUDAAN) use the term "correlated data" to refer not to the usual situation of variables being correlated, but in the sense of the inclusion of a case being correlated with the inclusion of another case. Is your DV dichotomous? Then GEE sound likely? For data that is not too discrepant from continuous, some form of the GLM such as repeated measures ANOVA would be a likely candidate approach.
