curerntly doing last minute homework for business school. and you, sir, just helped me pass one of my assignments. absolute legend for that, I must say. bigger contribution than what ghandi did for india. i mean it.
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?
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
Your explanation should win awards. This is SO helpful! Thank you so much for explaining this!

You're a hero! Thanks a lot.
your lecture is imaginable, thank you!
Saving me yet again. Thank you dragonfly.
"That seems mad." 😅
Thanks. Your explanation is so clear especially with the R.
Very good, I was also confused about the AIC selection loop.
thank you, you're the best
Thank you lad!
Oh My God. Thank you soooo much. This is very helpful.
Thanks this really helped with my assignment!
you really helped me (and my grade :D )
Is there a similar function for variable selection for dynamic regression with ARIMA errors ?
thank you
where is the files to work with this video?

I got iT I was confused about output of stepwise . Much clear now
Is step valid for glm's too (Mixed effect negative binomial model, for example)?

Non-parametric modeling? Just a guess. I have no real idea.
thanks so much sir
why in the end it gives me all the original variables ?
What library are you using?
Was asking myself the same question
What libraries do I need to execute this code?
library(datasets)
surely in this case 1024 different models is easily doable ;)
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?
It is (2^p)-1 , not 2^(p-1)
jhony rambo where p is the number of predictors or parameters?

What's the logic behind this?
