NettetLinear Models Practice. In the following, we will generate some data, with two features, that we’ll call d1 and d2. We will generate this data such that d1 and d2 are correlated. This means that they share some information, and so we can use this to property to try and predict values of d2 from d1, using a linear model to do so.
