The output variable, y, is a continuous numerical value. If we have more than one input/explanatory variable (x), as in the example that we are going to see, we call it multiple linear regression. The dataset that we'll use for this recipe, for lack of creativity, is lifted from the UCI website at http://archive.ics.uci.edu/ml/machine-learning-databases/wine-quality/.
