Probabilities And Poker

Steve Miller has a notebook on 5-card draw probabilities:

The population of 5 card draw hands, consisting of 52 choose 5 or 2598960 elements, is pretty straightforward both mathematically and statistically.

So of course ever the geek, I just had to attempt to show her how probability and statistics converge. In addition to explaining the “combinatorics” of the counts and probabilities, I undertook two computational exercises. The first was to delineate all possible combinations of 5 card draws from a 52 card deck, counting occurrences of relevant combinations such as 2 pair, a straight, or nothing in a cell loop.

Steve has made his notebook available for us.

Goodbye, gather and spread; Hello pivot_long and pivot_wide

John Mount covers a change in tidyr which mimics Mount and Nina Zumel’s pivot_to_rowrecs and unpivot_to_blocks functions in the cdata package: If you want to work in the above way we suggest giving our cdatapackage a try. We named the functions pivot_to_rowrecs and unpivot_to_blocks. The idea was: by emphasizing the record structure one might eventually internalize what the transforms […]
