Very good explanation but I'd still fail to draw that diagram correctly 😀

It is common practice in model building to remove the intercept by adding zero to the formula. However, if one does that in the example given here the correlation between the residuals increases (0.5 to 0.7). Can anyone where explain what causes that?

Hello. I want to implement the ridge regression method on a small dataset. but I want to get it by solving the model manually (by hand). How can I do it? I will be glad if you can help.

did u find a solution for that, I really need that right now
@kylmaz5782 Жыл бұрын
I found something, but I'm not entirely sure. You need to solve it through matrix form. You have to split the dataset using cross-validation (k-fold). Create your model by providing different lambda values and try to find the values. However, as I mentioned, for manual solution, you can only use the matrix form as far as I understand.@@CarpoMedia

Hi, thank you for these excellent lectures. At the end of this lecture, you mention applying ridge regression in practice in the next lesson, but it is not clear which video is the next in the sequence. It would be super helpful if you could add a link to the next lesson or even better - create a playlist with all the lessons in sequence. Thanks

0:30 AA^T = A is absolutely not what makes a matrix idempotent. Idempotency for matrices means A^2 = A. AA^T = A characterizes idempotency only for symmetric matrices.
@katolson8802 Жыл бұрын
She was not defining idempotency. “If, then” statements are not definitions.

Are the regression coefficients interpreted the same way as a traditional linear model (i.e., a one unit increase in a predictor X, increases outcome Y by the beta coefficient value)?
