    Very good, I was also confused about the AIC selection loop.

    Is step valid for glm's too (Mixed effect negative binomial model, for example)?

    Is there a similar function for variable selection for dynamic regression with ARIMA errors ?

  • @skynight113
    @skynight113 6 років тому

    did you write all the code yourself or did you have the base from something. I'd love to fiddle with it to get used to R more and do this to help remember a class I took 6 years ago.

    Thanks for the video - really helpful!!
    One question, if I want to investigate non-linear models (higher powers of the independant variables), is there a way to do that?

      Non-parametric modeling? Just a guess. I have no real idea.

    surely in this case 1024 different models is easily doable ;)

  • @abhishekajay9729
    @abhishekajay9729 6 років тому

    isn't it supposed to 2^(p-1) number of models, with p being the number of predictors instead of 2^p which you said when you mentioned 2^10 models?

    • @amcool8791
      @amcool8791 6 років тому +1

      It is (2^p)-1 , not 2^(p-1)

      Actually, I found it here for anyone to refer (however, where does the -1 come from?) math.stackexchange.com/questions/1117236/calculate-the-total-number-of-combinations-over-n-elements-where-the-number-of
