Adding variables to your multiple regression model 

Exceptional explanation, this is how this should always be taught

very good lecture, really enjoyed it ! thanks a lot !

Hiya Greg, any reason why you're still using maggritr pipes instead of native pipes? Great programme, btw. I'm looking forward to the rest of this series! One other thing, the initial linear model you had with the penguin data (not including species predictor in the model) is that a good example of Simpson's paradox? There is a downward trend when species is not considered, but once species is taken into account, the correlation between bill_length and bill_depth becomes positive.

Hi, Greg, how to plot the figure at 4:10 please. Thanks.

Hey Greg, love your video but PLEASE STOP THE SCRATCHING NOISES everytime you try to underline or point out something it nags me, idk if anyone's noticed but as a headphones users it feels like scratching with your nails on a chalkboard. Thank you. 😅
