The third model is constructed by CIBC, following their usual data mining procedure for a direct marketing campaign. The modeller at CIBC trained the model, and then passed on to us the validation result. The supervised learning algorithm of their choice is linear logistic regression. A considerable amount of time is spent on data preparation, including variable selection, variable transformation, and variable imputation. The first step in their modelling procedure is to significantly reduce the number of input variables by performing exploratory analysis on the data. This is done by having the modeller examine the relationships between the.
