comment Analysis of a longitudinal study where interventions are received at different time points
Since these programs are there for years, it's really difficult to find a sharp cut-off. Thanks Andy.

comment Analysis of a longitudinal study where interventions are received at different time points
@whuber you are right about it. Unfortunately we have only this now and definitely it is not a typical treatment-control version. The study is retrospective in nature. We have planned to compare the receivers of these programs to a dummy control group created by propensity score matching using some background variables- I think that is what we can do at best now. The fact that really very few have received more than one program, keeps our hope alive! I am wondering what kind of model we should use to find the above mentioned aspects from this data.

comment Similarities and dissimilarities between optimal scaling procedures in CATPCA and MCA
Could you please illustrate how the quantification is done in both processes? I know for CATPCA the quantification is done so that the correlations between the quantified variables are maximized. Then how the initial quantification is set? What is the procedure for quantification in MCA?

comment Why do we use only the first component scores to construct different indices?
Actually I meant indices like the asset indices. Here usually the scores of the first component is divided into quintiles.

Thank you so much for the reference. I'll try to learn it and yes I understand that it will take time. But thanks for you hints.

comment Analysis of spatial data over time and space
I am also quite concerned about the over-fitting problem that might occur by using the latitude and longitude as regressors.
