Hi, I get the following error when coding the example from the video in my Jupyter Notebook: Is there something I have done wrong? I get it right when performing simple linear regression but I get the error with multiple linear regression. I have tried with Jupyter Notebook from Google Colab and also in my usual VIM editor. I get the error with both. Thank you in advance,

Hey María, Thank you for your response! I now realized where the problem is. The following line of code: x1 = [['SAT','Rand 1,2,3']] should be substituted with x1 = data[['SAT','Rand 1,2,3']] Notice there is the word data in front. Without it, the variable x1 becomes simply a list, containing another list, containing two strings :) Hope this helps! Kind regards, 365 Hristina

Hi Hristina, Thank you very much for your answer. I am not using the same Jupyter notebook. I have opened a new one in Google Colab and copied the code. I don't have it installed. Could this be the problem? I have also made a copy with VIM and run it from the Linux terminal and I get the exact same error when running the multiple linear regression. No problem at all with he simple one. Here you have my answers: 1. Done. I still get the error. 2. Yes, I get the same output >>> (numpy.int64, numpy.int64) 3. My version of "statsmodels" is 0.13.2. Kind regards,

Oh, it's true! Hahaha. Thank you very much. Today I couldn't understand why the rest of the exercises on multiple linear regression were working properly. :) Sorry for the inconvenience. Kind regards,
