Dear list!

 

I am reviewing a very old material of 420 female alcoholic patients. Each patient has up to 2-5 female controls (mostly 5) matched on age at admission, place of residence (Stockholm county) at admission, level of education and socioeconomic group. The common variables of interest are a mixture of nominal, ordinal and scale variables (mostly health/ sickness related spanning over an observation period of several decades).  I would like to test the differences between the patients and controls in these variables taking into account the more stable estimates of the controls. Will this type of testing be different for nominal, ordinal and scale variables?

 

I remember asking this to the list several years ago and , if I remember correctly, getting an answer from Martha Garcia-Granero suggesting “conditional regression” Since then I was swamped in other work and the material receded into oblivion. Now  I would like to tackle this again. I have never heard of “conditional regression”. Can anyone explain? Is this a relevant method or are there better methods? Any hints will be much appreciated.

 

best
