Master core R skills to become a machine learning scientist Start Learning for Free What are coefficients? In the red square, you can see the values of the intercept (“a” value) and the slope (“b” value) for the age. These “a” and “b” values plot a line between all the po...
par(mfrow=c(1,1)) plot(predmodel.test.qda$posterior[,2], predmodel.test.qda$class, col=test$Survived+10) Gives this plot: Conclusion LDA and QDA work well when class separation and normality assumption holds true in the dataset. If the dataset is not normal then Logistic regression has...
