Questiоn 1: Full Mоdel (10 pоints) (1а) Creаte а correlation matrix plot that includes all twelve variables in the dataset. (1b) Based on the plot above in 1a, identify which two predicting variables have the strongest negative correlation. (1c) Fit a logistic regression model (use logit link function) with quality as the response variable and all other variables as predicting variables. Do not include an intercept! Call it model0. Display the summary table for the model. Note: Remember to use dataTrain as your data set. (1d) Fit a logistic regression model (use logit link function) with quality as the response variable and all other variables as predicting variables. Do include an intercept! Call it model1. Display the summary table for the model. Note: Remember to use dataTrain as your data set. (1e) Which coefficients are not statistically significant at the 95% confidence level in model1? Briefly explain your reasoning. (1f) Interpret the estimated sulphates coefficient in the context of this model in terms of log-odds in model1.
