Probabilistic Standings Simulations – Mixed Auction LABR
Introduction
Well, we are down to the final week of fantasy baseball. After a short 60 game season in 2020, we are blessed to be approaching game 162 here in 2021!
We here at RotoGraphs, are hoping that you are right in the thick of the competition for your league’s fantasy championship title. For me – I am right in the middle of an intense battle with one of the legends of rotisserie baseball, Ron Shandler, as well as our own Jeff Zimmerman.
The league that I am referring to is the Mixed Auction LABR league. I was one this division of LABR’s inaugural members back in 2020.
Above is a photograph of some of the participants of the live 2020 auction draft from Tampa, Florida. Due to COVID, this year’s draft was held online. LABR is one of the longest running (if not THE longest currently running) expert leagues of rotisserie baseball. It is an honor simply to be invited to compete.
The Mixed auction LABR league is a very standard 12-team 5×5 rotisserie league. We use the standard scoring categories (R, RBI, HR, SB, BA, W, K, SV, ERA, WHIP), and standard rosters (14 B, 9 P). Scoring periods are weekly, trading is allowed, and the initial draft is of the auction variety. Last year, I went into great detail recapping my draft – a two-part article that can be found here and here.
As many of you might already know, as a risk management actuary – my day job consists of running simulation models to recommend purchasing decisions to the upper management of my company. I simulate possible fires, hurricanes, medical malpractice claims, and other liabilities that we may be on the hook for.
Borrowing several actuarial methods, I adapted some of these models in order to develop a proprietary in-season fantasy baseball tool. It is a probabilistic final standings simulator. Using the current league accumulated standings, a source of projected ROS statistics, a volatility and a correlation model – I run 4000 iterations of what might happen for the remainder of the season.
