@whuber I would also like to know your thought.

comment Analysis of a longitudinal study where interventions are received at different time points
@Andy, The main problem that I am facing is that the same program was received at different times by the students. So, I may calculate the CGPA before and after the program for the program receivers but how can I calculate the same for the non-receivers? Otherwise is it possible to compare the these two groups? Without a fixed time point of implementing the program, how can I find a before and after CGPA for control group who did not receive any program?

Yes Andy, there are some, actually they consider several things. But can we see if the effect was instant but temporary or instant and durable or delayed but durable or delayed but temporary with regression discontinuity design?

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.
