ARGH Power Ratings
The ARGH Power Ratings are a sports rating system created by Stewart Huckaby in 1990 and designed to identify the best team from within a closed system. They are most closely identified with NCAA football. The system is designed to be both predictive and retrodictive in nature, although in practice it has proven to be more strongly predictive than retrodictive. The ARGH Power Ratings evaluate teams taking into account a team's wins and losses, its points scored both for and against, its schedule, and the location of the team's games. It is unusual in that for the purposes of providing meaningful ratings throughout the season it seeds teams based on several stated criteria, including records from the previous two seasons, the previous year's strength of schedule, the number of returning starters, whether the head coach is returning, whether the starting quarterback is returning, and published recruiting rankings from several preseason publications. Preseason seedings disappear over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Rating System
A sports rating system is a system that analyzes the results of sports competitions to provide ratings for each team or player. Common systems include polls of expert voters, crowdsourcing non-expert voters, betting markets, and computer systems. Ratings, or power ratings, are numerical representations of competitive strength, often directly comparable so that the game outcome between any two teams can be predicted. Rankings, or power rankings, can be directly provided (e.g., by asking people to rank teams), or can be derived by sorting each team's ratings and assigning an ordinal rank to each team, so that the highest rated team earns the #1 rank. Rating systems provide an alternative to traditional sports standings which are based on win–loss–tie ratios. In the United States, the biggest use of sports ratings systems is to rate NCAA college football teams in Division I FBS, choosing teams to play in the College Football Playoff. Sports ratings systems are also used to hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prediction
A prediction (Latin ''præ-'', "before," and ''dictum'', "something said") or forecast is a statement about a future event or about future data. Predictions are often, but not always, based upon experience or knowledge of forecasters. There is no universal agreement about the exact difference between "prediction" and " estimation"; different authors and disciplines ascribe different connotations. Future events are necessarily uncertain, so guaranteed accurate information about the future is impossible. Prediction can be useful to assist in making plans about possible developments. Opinion In a non-statistical sense, the term "prediction" is often used to refer to an informed guess or opinion. A prediction of this kind might be informed by a predicting person's abductive reasoning, inductive reasoning, deductive reasoning, and experience; and may be useful—if the predicting person is a knowledgeable person in the field. The Delphi method is a technique for elicitin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retrodiction
Retrodiction is the act of making a prediction about the past. It is also known as postdiction (but this should not be confused with the use of the term in criticisms of parapsychological research). Activity The activity of retrodiction (or postdiction) involves moving backwards in time, step-by-step, in as many stages as are considered necessary, from the present into the speculated past to establish the ultimate cause of a specific event (for instance, in the case of reverse engineering, forensics, etc.). Given that retrodiction is a process in which "past observations, events and data are used as evidence to infer the process(es) that produced them" and that diagnosis "involve going from visible effects such as symptoms, signs and the like to their prior causes",Einhorn & Hogarth (1982), p.24. the essential balance between prediction and retrodiction could be characterized as: ::retrodiction : diagnosis :: prediction : prognosis regardless of whether the prognosis is of the ...
