Drafting the Best Starting Lineup in Fantasy Football by Taking into Account Uncertainty in the Projections: An Optimization Simulation

In a previous post, I showed how to determine the best starting lineup to draft using an optimizer tool.  The optimizer identifies the players that maximize your projected points within your risk tolerance.  The optimizer does not take i...

Bayesian Estimation of Correlation – Now Robust!

So in the last post I showed how to run the Bayesian counterpart of Pearson’s correlation test by estimating the parameters of a bivariate normal distribution. A problem with assuming normality is that the normal distribution isn’t robust against outliers. Let’s see what happens if we take the data from the last post with the finishing times...
