Fоr questiоns 13 - 15 pleаse use the descriptiоn below. A dаtа analyst is interested in building a model to predict the default risk of credit card applicants. The company database has large amounts of demographic and financial data on past and current credit card holders and whether they have defaulted. She prepares a data set of 1000 observations for a preliminary analysis. She creates a binary variable called default. It is 1 if the person had defaulted and 0 otherwise. For analysis, she decides to use both Logistic Regression and Linear Support Vector Machine (Linear SVM). Her goal is to select a model with the best predicitive accuracy between the two approaches. After some trial and error she identifies a set of independent variables that she will use in all models without further variable selection. She needs help from you to use the 1000 observations effectively to reach her goal.
