Case interview #1: Mail sending

2 Answers

I'm sorry if i understood the question wrong. But wont the option 2 better in every scenario? It costs the company 40c to send the mail with 90% accuracy. So to have the same reach to number of people as of option 1 (say we want 100 people to get the mail), we just need to send the mail to 111.11 people in option 2. With 90%, it will reach 100 people and will cost $44.44 whereas it will cost $50 with option 1. It will not matter if only the accuracy rate was 80% in option 2.

there should have two utility functions, one for number of people received mail, one for the money spend: U1=g(X) - f(0.5X); U3=g(0.9X) - f(0.4X). if money is the most important constraint, function f would be a very steep function, thus U3 > U1; if people is the most important, g would be a very steep function, thus U1 > U3. if we have g and f defined, we can set U1=U3,

You have 1000 randomly sampled data points. The goal is to try to build a regression model with one response variable from k regressor variables. Which is better? 1. (Bayesian Regression) Using the first 500 samples to estimate the parameters of an assumed prior distribution and then use the last 500 samples to update the prior to a posterior distribution with posterior estimates to be used in the final regression model. 2. (OLS Regression) Use a simple ordinary least squares regression model with all 1000 regressor variables.
