Polynomial Regression in R

[@richardnz100]

Great video! Thanks very much, Tom. Ideas very clearly expressed. Enjoyable to watch and listen to (which is quite an achievement considering the subject matter!!). Well done!

+richardnz100 Many thanks for your kind words Richard. We will be making all of the videos (along with multi-choice etc) available on a Moodle site within the next couple of months.

How to calculate r² for degree 2 equation ???

[@umbnmbu4679]

@5:05 to interpret this: if x increases by 1, y increases by 3.05 times., but what about the relationship of the second order polynomial equation @5:32, how can this be interpreted? especially the (-3.22*x2).

[@splekort]

Can anybody point me to a link on how to compute the r2 in quadratic fit manually?

[@rokaskarabevicius]

Beautiful explanation! Thank you!

[@mathgmathg923]

can you make a playlist on CROSS VALIDATION, LDA/QDA, PCA,SVM i would really appreciate it!!!! thanks in advance
