Assignment 5 

BostonFinance Minicase (continued..) and comparison

Background

In the last assignment, in your role as Credit Development Manager (CDM) for BostonFinance, you asked your Data Science Team (DST) to run the K-NN algorithm for K=10 and a cutoff value of 0.0001. Now, you take only the results from the K=10 with a cutoff of 0.0001 analysis and present them to your Supervisor (without discussing any of the results from the Final Cut Predictive Model or those from the K-NN analysis using the BEST K).

Tasks

1. What parallels or similarities do you see between your decision as CDM to only selectively present the results of the K=10 and a cutoff value of 0.0001 analysis and NASA’s decision to ignore the dissenting voice (Allan McDonald and Roger Boisjoly) regarding the Challenger launch (the Challenger video especially between minutes 22:00 - 28:40)?

2. What could be the underlying motivations for these two decisions described above?
