Red and White Wine Data Analysis - Predict Quality of Wine

Model analysis is wide-spread and has many applications in various fields. The intention of this analysis on red and white wine of the Vinho Verde varietal from Portugal is to predict the quality of the wine based on the predictors. This topic is of interest so results can be shared with patrons that want to buy and consume higher quality wine and how they can find relationships between the variables and the quality. Wine manufacturers would be interested so they can produce wine that more people will enjoy. The analysis is done through comparing several models, including traditional linear models, Least Absolute Shrinkage and Selection Operator (LASSO) models, and the more sophisticated Gaussian process. Model performance will be compared through a training/test set split, as well as k-fold cross validation, and, where applicable, the Akaike Information Criterion (AIC).
