The linear regression model that I’ve been discussing relies on several assumptions. In Section 15.9 we’ll talk a lot more about how to check that these assumptions are being met, but first, let’s have a look at each of them. Normality. Like half the models in statistics, standard linear regression relies on an assumption of normality.
