Last night, Harlan Harris and I gave a talk at the NY Predictive Analytics meetup. Despite the rain there was a good turn out and people seemed to both enjoy and benefit from the presentation.

A great way to visualize the results of a regression is to use a Coefficient Plot like the one to the right. I’ve seen people on Twitter asking how to build this and there has been an option available using Andy Gelman’s coefplot() in the arm package. Not knowing this I built my own (as… Continue reading

There are a few different ways to tip, check (only one person did this), credit card at the door, pre-tipping with a credit card and cash. As seen in these boxplots, cash tippers were the highest, on average. Pre-tippers, who really… Continue reading
