At Altair we pride ourselves on the cohesive, friendly, well-oiled and fun team we have built over the years. We rely on each other’s expertise and at least once per month, one of our employees will conduct a training session over lunch that we cleverly call “Lunch and Learn”. Each topic is a specialty of the employee doing the presentation. This month’s topic was an overview on our Model Development process presented by our Vice President of Analytics, David Hunter. David’s interesting and varied background not only makes him fun to hang out with and talk to it gives him perspective and insight rarely seen in your typical stats type.
He has been in a band and cut a record. He is an avid cyclist and world class mechanic, as well as generous. Last weekend he checked over 120 kids bikes at a bike rodeo and then made time to help a little boy learn to ride his bike. He’s been back in the US for 4 months having recently, lived in Lodz Poland for almost 2 years. And of course, he has a ton of analytics and modeling experience both on the client-side for BellSouth and as a manager with Equifax.
During today’s Lunch and Learn session, David used an example of a recent custom model to explain how to read a gains chart. The model was developed to predict the likelihood of booking a refinance loan for a large mortgage lender. The model has predicts book rates that are 2.6 to 4 times higher than the baseline. A 400% lift! So, why aren’t mortgage companies across the country knocking down our door asking about our mortgage models? I don’t know, but they should. We’ve built shelf models for Prime Refinance, FHA Refinance and Reverse Mortgage as well as twice that many custom in just the last 6 months.
