    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)?

    Great video, how to you add the interaction between age and drug to the fit model?

    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! :)

    I saw someone using an i. before the initial independent variable, what does this exactly means?
    Thank you!
