Context: eBay Auctions

Using the eBay auction data (file eBayAuctions.csv) with variable Competitive as the outcome variable, partition the data into training (60%) and validation (40%).

Set the seed for the random number generator for reproducing the partitions as random_state=1.

Run a classification tree, using the default settings of DecisionTreeClassifier. Looking at the validation set, what is the overall accuracy? What is the lift on the first decile?
