I presented my paper in a conference, I used Poisson model to see the relationship between "number of comments" users receive for their topic with the "number of days until posting the second topic". In fact I wanted to see how the feedback affects individuals to come back and post in the website.
one of the audience told me I can use survival analysis. I have never heard about it and I bought a book to read but it will take a lot of time to know which model fits to my data.
Would you please someone let me know if for the following sample dataset I can use survival analysis? if yes, which model and what steps I need to follow to do survival analysis and interpret the outcomes.
Also, should I delete the last observation for each user from dataset since they do not have any survival time? should I delete the users who just participated one time since they do not have any value for survival time column?
I really will appreciate any help since your help can save a lot of time for me.
