Preamble

Consider the wine quality dataset from UCI Machine Learning Respository ¹. We will focus only on the data concerning white wines (and not red wines). Dichotomize the quality variable as good, which takes the value 1 if quality ≥ 7 and the value 0, otherwise. We will take good as response and all the 11 physicochemical characteristics of the wines in the data as predictors. Develop a good classifier and justify your choice of that classifier.
