Machine Learning - Odds Ratios and Log(Odds Ratios), Clearly Explained!!!

Odds Ratios and Log(Odds Ratios) are like R-Squared - they describe a relationship between two things. And just like R-Squared, you need to determine if this relationship is statistically significant. This StatQuest goes over all these details so that you are ready for any odds ratio and log(odds ratio) situation that you might get yourself into!!! This StatQuest builds on the concepts covered in...
