Sports Betting Systems
Sports betting systems are sets of events that when combined for a particular game for a particular sport represent a profitable betting scenario. Since sports betting involves humans, there is no deterministic edge to the house or the gambler. Systems supposedly allow the gambler to have an edge or an advantage. Sportsbooks use systems in their analysis to set more accurate odds. Therefore, the novice gambler may believe that using a system will always work, but it is the general consensus that at some point the oddsmakers will have adjusted for the system to make it no longer profitable. Very short-lived systems are called trends. Any single event that estimates a selection to have a higher likelihood of winning is called an angle as they are meant to be used in conjunction with other angles and trends to produce systems. Overview Systems can be deceiving. Any sample space can be constrained enough with meaningless criteria to create the illusion of a profitable betting syst ...

Sports Betting
Sports betting is the activity of predicting sports results and placing a wager on the outcome. Sports bettors place their wagers either legally, through a sportsbook or bookmaker (colloquially known as "bookies"), or illegally through privately run enterprises. The term "book" is a reference to the books used by wage brokers to track wagers, payouts, and debts. Many legal sportsbooks are found online, operated over the Internet from jurisdictions separate from the clients they serve, usually to get around various gambling laws (such as the Unlawful Internet Gambling Enforcement Act of 2006 in the United States) in select markets, such as Las Vegas, or on gambling cruises through self-serve kiosks. There are different types of legalized sports betting now such as game betting, parlays props and future bets. They take bets "up-front", meaning the bettor must pay the sportsbook before placing the bet. Due to the nature of their business, illegal bookies can operate anywhere but ...

Sabermetrics
Sabermetrics (originally SABRmetrics) is the original or blanket term for sports analytics in the US, the empirical analysis of baseball, especially the development of advanced metrics based on baseball statistics that measure in-game activity. The term is derived from the movement's progenitors, members of the Society for American Baseball Research (SABR), founded in 1971, and was coined by Bill James, (in 1980, according to SABR.org), who is one of its pioneers and considered its most prominent advocate and public face. The term moneyball refers to the use of metrics to identify "undervalued players" and sign them to what ideally will become "below market value" contracts; it began as an effort by small-market teams to compete with the much greater resources of big-market ones. Early history English-American sportswriter Henry Chadwick developed the box score in New York City in 1858. This was the first way statisticians were able to describe the sport of baseball by ...

Arbitrage Betting
Betting arbitrage ("sure bets", sports arbitrage) is an example of arbitrage arising on betting markets due to either bookmakers' differing opinions on event outcomes, or errors. When conditions allow, by placing one bet per each outcome with different betting companies, the bettor can make a profit regardless of the outcome. Mathematically, arbitrage occurs when there are a set of odds, which represent all mutually exclusive outcomes that cover all state space possibilities (i.e. all outcomes) of an event, whose implied probabilities add up to less than 1. Background Arbitrage betting involves relatively large sums of money, given that 98% of arbitrage opportunities return less than 1.2%. The practice is usually detected quickly by bookmakers, who typically hold an unfavorable view of it,{{Cite web, url=https://economics.yale.edu/sites/default/files/files/Undergraduate/Nominated%20Senior%20Essays/2015-16/Schwartz_Avery_SeniorEssay%202016.pdf, title=Arbitrage in the European Soc ...

Virtual Sports
A sports video game is a video game that simulates the practice of sports. Most sports have been recreated with video games, including team sports, track and field, extreme sports, and combat sports. Some games emphasize playing the sport (such as ''EA Sports FC'', ''eFootball'' and ''NBA 2K''), whilst others emphasize strategy and sport management (such as ''Football Manager'' and '' Out of the Park Baseball''). Some, such as ''Need for Speed'', ''Arch Rivals'' and ''Punch-Out!!'', satirize the sport for comic effect. This genre has been popular throughout the history of video games and is competitive, just like real-world sports. A number of game series feature the names and characteristics of real teams and players, and are updated annually to reflect real-world changes. The sports genre is one of the oldest genres in gaming history. Game design Sports games involve physical and tactical challenges, and test the player's precision and accuracy. Most sports games attempt to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Statistical Association Football Predictions
Statistical association football prediction is a method used in sports betting to predict the outcome of football matches by means of statistical tools. The goal of statistical match prediction is to outperform the predictions of bookmakers, who use them to set odds on the outcome of football matches. The most widely used statistical approach to prediction is ranking. Football ranking systems assign a rank to each team based on their past game results, so that the highest rank is assigned to the strongest team. The outcome of the match can be predicted by comparing the opponents’ ranks. Several different football ranking systems exist, for example some widely known are the FIFA World Rankings or the World Football Elo Ratings. There are three main drawbacks to football match predictions that are based on ranking systems: # Ranks assigned to the teams do not differentiate between their attacking and defensive strengths. # Ranks are accumulated averages which do not account for ...

American Football
American football, referred to simply as football in the United States and Canada and also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular American football field, field with goalposts at each end. The offense (sports), offense, the team with possession of the oval-shaped Ball (gridiron football), football, attempts to advance down the field by Rush (gridiron football), running with the ball or Forward pass#Gridiron football, throwing it, while the Defense (sports), defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance the ball at least ten yard, yards in four Down (gridiron football), downs or plays; if they fail, they turnover on downs, turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the Glossary of American football#drive, drive.

Correlation Does Not Imply Causation
The phrase "correlation does not imply causation" refers to the inability to legitimately deduce a cause-and-effect relationship between two events or variables solely on the basis of an observed association or correlation between them. The idea that "correlation implies causation" is an example of a questionable-cause logical fallacy, in which two events occurring together are taken to have established a cause-and-effect relationship. This fallacy is also known by the Latin phrase ''cum hoc ergo propter hoc'' ('with this, therefore because of this'). This differs from the fallacy known as '' post hoc ergo propter hoc'' ("after this, therefore because of this"), in which an event following another is seen as a necessary consequence of the former event, and from conflation, the errant merging of two events, ideas, databases, etc., into one. As with any logical fallacy, identifying that the reasoning behind an argument is flawed does not necessarily imply that the resulting c ...

Dependent And Independent Factors
A dependant (US spelling: dependent) is a person who relies on another as a primary source of income and usually assistance with activities of daily living. A common-law spouse who is financially supported by their partner may also be included in this definition. In some jurisdictions, supporting a dependant may enable the provider to claim a tax deduction. In the United Kingdom, a full-time student in higher education who financially supports another adult may qualify for an Adult Dependant's Grant. Taxation In the US, a taxpayer may claim exemptions for their dependants.

Multivariate Linear Regression
The general linear model or general multivariate regression model is a compact way of simultaneously writing several multiple linear regression models. In that sense it is not a separate statistical linear model. The various multiple linear regression models may be compactly written as : \mathbf = \mathbf\mathbf + \mathbf, where Y is a matrix with series of multivariate measurements (each column being a set of measurements on one of the dependent variables), X is a matrix of observations on independent variables that might be a design matrix (each column being a set of observations on one of the independent variables), B is a matrix containing parameters that are usually to be estimated and U is a matrix containing errors (noise). The errors are usually assumed to be uncorrelated across measurements, and follow a multivariate normal distribution. If the errors do not follow a multivariate normal distribution, generalized linear models may be used to relax assumptions about Y and ...

Statistical
Statistics (from German language, German: ', "description of a State (polity), state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of statistical survey, surveys and experimental design, experiments. When census data (comprising every member of the target population) cannot be collected, statisticians collect data by developing specific experiment designs and survey sample (statistics), samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
