In this chapter, you will learn when to use linear regression, how to use it, how to check the assumptions of linear regression, how to predict the target variable in test dataset using trained model.
Finally, let’s bust out a linear regression. Thelm()function, which fits a linear model to the data, has some truly bizarre syntax using a~character. The docs say, “The tilde operator is used to separate the left- and right-hand sides in model formula. Usage: y ~ model.” I don...
