Adding variables to your multiple regression model

Linear regression is considered to be simple regression if only one explanatory variable is used and multiple regression if the model includes more than one explanatory or independent variable. In this video we explore how to add additional categorical variables and numeric variable to your linear regression model. If you are interested in statistical analysis then learning how to undertake a multiple regression analysis will be of interest.

I'm about 60% through a master's degree in Data Analytics, and I attribute a lot of my course success to your videos. Thank you! Also, I hated R before running across your channel and now I use it instead of python for any course I take.

wow - thanks for the great feedback. I'm glad that I could help!!

[@wizardaka]

Exceptional explanation, this is how this should always be taught

[@osmanhabeeb9892]

Thank you very much. Why do the prediction lines for the Gentoo specie have a different angle compared to the two other species, while having the same estimate for bill length ? Could you please demonstrate how to create the figure for the prediction lines and observations of those species?"

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

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.

please where is pdf file .thank you

[@yordanosgizachew9356]

I am wondering the same thing.

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. 😅
