    Great trick with Polynomials and MSE's!

    Thank you very much for the detailed and helpful video. Is there a way to interpret the delta value of the cv.glm() function without comparing it with other models (e.g. as done in your video)? For example, can I simply run the LOOCV on a model and then interpret the delta value (if it's good/bad)? Since the MSE depends on the metric/unit, you can't really derive much from this unstandardized value by itself, right? Thank you in advance!!!

    I found this tutorial extremely helpful, how do you calculate the misclassification rate?

    Hi Abbass!
    Excellent tutorial. I have a question: how can I calculate R saquared from LOOCV and K-Fold CV results?
    thanks a lot!

    Thank your for the useful video. Do you know how to do k-fold cross validation for neural network to predict a parameter in R?

    Does the interaction term affect the k -fold cross validation?

    hell thanx you for your tutoriel
    is there any way to do the LOOCV using SPSS ?

    would you please explain how to apply 10-fold cross-validation in KNN and Random forest?

    Why was the K-fold or 10-fold repeated 10 times, I wonder ?

    Hey where are you? Why don't you make new videos on R? We miss your teaching a lot. Please come with new video Sir.

      Hi! This works fine for linear models! I was wandering how one should do this for logistic regression, since we want the accuracy and not the MSE. Could you help on this?

    Hello, Abbass. Can I send you e-mail and ask some questions about cross validation in R? Thanks a lot!
