NRL S2016 R12-13 Results

Summary

Since there were only 4 games in round 12, I thought I would post the results of round 12 & 13 together to save myself some time.

Round 12 was a very poor predictive round (1 out of 4 correct) owing to the models inability to properly account for team changes due to representative matches (State of Origin). However; we did better than the bookmaker (5 out of 7) in round 13 after I put a bit more weight on the team dynamic factor/s to account for player absences due to Origin.

Although retrospectively we know the model did well in round 13, at the time I chose to abstain from betting because some (key) team players were being rested up after Origin.

OK so lets take a detailed look at results for round 12-13 and the results to date:

Predictive Results

Given:

mTP = Models true positives

mFP = Models False positives

mPrec = Models precision (equivalent to accuracy in this case)

bTP = Bookmakers true positives

bFP = Bookmakers False positives

bPrec = Bookmakers precision (equivalent to accuracy in this case)

For those who have contributed to the initial bank, the break down of your contribution and what you are currently entitled to is below. It’s pretty self explanatory with the main column being ‘entitlement’. This is how much you are entitled given your initial contribution. The gain (in dollars) is the amount of profit/loss you have currently made on your investment
