Показать описание
In this video I finish the model I started in the earlier video and create a confusion matrix then find the accuracy, prediction, and recall measures. I finish the presentation by creating a ROC (receiver operating characteristic) curve.
The link for the Excel file I used is provided below as a Google Sheets file. Do download it please open it, go to File- Download As - Excel

Thank you very much for sharing this in depth tutorial, it has proven to be invaluable to me.

I wanted to ask, if possible, after determining the efficacy of the model, would you be willing to publish a tutorial detailing how this can be utilised in predictive practice?

Your time and consideration would be appreciated.

Thanks for such a great video, in my case the solver is not able to solve it, it is showing an error that one of the cells in the worksheet became an error value when solver tried certain values.

Please help me what to do in this case

Using same data we can also find out R2 of the model but how do you find out p-value from this?

Sorry sir, i have little question here about the evaluation model.
This video explain us about regression and evalute with confusion matrix. How it works? Is it able to do regression evaluation using a confusion matrix?
Why not use MSE, MAE, etc?
Thank you sir

How do you decrease the sum of the log likelihoods more? Mine comes out to be -1800 to after the solver ran through it -1766..

Hi sir, to make sure, this is ordinal logistic regression right? This is not the multinomial logistic regression if I got it correctly.
