Thank you very much for the very informative video! Sorry it the question is stupid: at 2:56 you added another variable of age. But why the result for drug have changed afterwards? Before adding age, the haz.ratio was 0.133, and 95% conf. interval was (0.045, 0.314), and after they became 0.105 and (0.043, 0.256)?
So is the idea here that we don't want the two lines to be crossing each other? What about if they exhibit a non-random pattern against the variable time? Some more detail regarding the interpretation would be very very much appreciated! :)
very helpful, STATA is really a friendly software.

Hi xiao did you find the answer for this? Im here cuz I got this question while doing an analysis.
Useful and clear thank you
Very helpful and clear video thanks!
Great video, how to you add the interaction between age and drug to the fit model?

Very great video man. Thanks alot
Very helpful
I saw someone using an i. before the initial independent variable, what does this exactly means?
