Trojan Horse: Unexpected Style at Your Door1 Case Questions: Decision Tree 1. Using the training data, build a decision ... tree model to predict probability that a member will purchase a box. If you set a cut-‐off threshold of .15, how many members would you target in the training set? Which ones? There are 3 leaves we target with 36 + 107 + 189 = 332 members in the training set. The leaves are: • R < 16 && ClassicGentleman >= 1 && Rugged >=2 • R < 16 && ClassicGentleman >= 1 && Rugged <2 • R < 16 && ClassicGentleman < 1 && R < 8 We can simplify the description of these members to: • R< 16 and ClassicGentleman >= 1 • R < 8 and ClassicGentleman < 1 2. What is the R2 of your model? In simple words, what does this mean? The R2 is 10.5% on the training data, 7.9% on the testing data. In words, this means that the model only explains about 10% of the variability in the data, which doesn’t seem like very much. We’ll see later, though, that it still has enough classification accuracy to improve our marketing campaign. 3. Examine each of the split variables. Do they make intuitive/business sense? Explain each one. • Splitting on R is intuitive. Customers who haven’t purchased in a long time probably don’t like the service and won’t purchase again. • Splitting on ClassicGentleman probably occurs because members who like “ClassicGentleman” items like the current box. • The box is also probably more on the “Rugged” side, explaining why customers who purchase from Rugged are more likely to buy. • The final split is somewhat more confusing. Customers who haven’t bought a ClassicGentleman product, but have purchased something within the last 8 months do tend to like the box. This split merits further investigation. One possibility, e.g., is that members in this box are new to the service and, hence haven’t had the chance to buy a ClassicGentleman product, but would if they were offered one. If they had, they’d be part of the other leaves. These splits also suggest that the current box is very “ClassicGentleman”, but has “Rugged” elements to it. Importantly, this description of the box was generated [Show More]
