Snooker scores from two complete rounds of graded teams competition are analysed to detect differences in scores which can be attributed to various external factors, in order to quantify the factors relevant to a player's score in a game of snooker. Such factors are assessed subjectively at present. While each factor examined is found to be significant in one or more of the various grades, it is only in the highest grade that a clear pattern to matches can be identified.

Syftet med det här arbetet är att undersöka hur väl logistisk regression kan användas för att prediktera vinnaren i en snookermatch. Detta görs med hjälp av statistik över spelarna samt resultat från tidigare matcher och turneringar. En mängd möjliga förklarande variabler presenteras som exempelvis ranking, antal vunna matcher, hemland, typ av turnering, prissumma och omgång (final, semifinal, et cetera). Även tvåvägs-interaktioner mellan variablerna undersöks. Modeller tas fram utifrån hur de presterar i AIC, BIC, residualavvikelse samt Hosmer-Lemeshow-testet. Därefter mäts deras prediktiva förmåga hos ett helt nytt datamaterial med hjälp av noggrannhet, sammanblandningsmatriser och AUC. Resultatet ger flera olika modeller, men den som i slutändan väljs är en modell med bara en förklarande variabel – skillnaden i spelarnas ranking. Modellen hade rätt i sina prediktioner i 60 procent av fallen. Snooker visar sig vara en relativt svårpredikterad sport, jämfört med exempelvis fotboll och hockey, med flera oväntade utfall där den överlägset bättre rankade spelaren förlorade. Modellen är visserligen bättre än vad att godtyckligt gissa vilken spelare som kommer vinna hade presterat, vilket får ses som ett lägsta mått på användbarhet. / This study aims to investigate how well logistic regression can be used to predict the winner in a snooker game. This is done using statistics on the players and results from previous matches and tournaments. A range of possible explanatory variables are presented, such as ranking, number of wins, country, type of tournament, prize money, and round (final, semifinal, et cetera). Two-way interactions between the variables are also examined. Models are developed based on their performance in AIC, BIC, residual deviation, and the Hosmer-Lemeshow test. Then, their predictive ability is measured on an entirely new data set using accuracy, confusion matrices, and AUC. The result produces several different models, but the one ultimately chosen is a model with only one explanatory variable – the difference in the players' rankings. The model was correct in its predictions in 60 per cent of cases. Snooker turns out to be a relatively difficult sport to predict, compared to, for example, football and hockey, with several unexpected outcomes where the significantly better-ranked player lost. The model is at least better than randomly guessing which player would win, which should be seen as the lowest measure of usefulness.

A dissertação analisa três contos de João Antônio Meninão do Caixote, Malagueta, Perus e Bacanaço e Visita , ambientados em salões de jogo de sinuca na cidade de São Paulo. Esses contos foram publicados no livro de estreia do autor, Malagueta, Perus e Bacanaço, em 1963, e apresentam narrativas com personagens que vivem do jogo, utilizando toda sorte de artimanhas no universo da malandragem. Baseando-se em alguns fundamentos da semiótica das paixões, inscrita dentro da chamada Escola de Paris, de linha greimasiana, a análise investiga os estados de alma que resultam das transformações que ocorrem ao longo das narrativas. Como suporte de fundamentação teórica, utiliza principalmente os conceitos desenvolvidos por A. J. Greimas e J. Fontanille, Diana Pessoa de Barros, José Luiz Fiorin, Elizabeth Harkot-de-la-Taille e Claude Zilberberg. O estudo se inicia com a apresentação dos fundamentos teóricos da semiótica das paixões e segue com a análise dos três contos, com o exame do modo como as instaurações dos sentimentos de orgulho e seus correlatos e de avidez e seus correlatos acompanham as transformações de estados dos sujeitos das narrativas. A análise se completa com a aplicação dos conceitos de missividade e fluxo discursivo, de Zilberberg, e com o questionamento dos confrontos entre os universos da norma social e da malandragem que permeiam os objetos de estudo. / This dissertation analyzes three short stories by João Antônio Meninão do Caixote, Malagueta, Perus e Bacanaço and Visita , within the context of a snooker hall in the city of São Paulo, in Brazil. These short stories were included in the authors first publication, Malagueta, Perus e Bacanaço, in 1963, and present narratives with characters that make their living from the game, employing all the luck of the hustle within the universe of deceit, of trickery. Based on a selection of Greimas fundamentals on the semiotics of passion, ingrained in the so-called School of Paris, the analysis investigates the states of the soul stemming from the transformations that arise throughout the narratives. To sustain the theoretical foundations, it uses, mainly, the concepts developed by A. J. Greimas and J. Fontanille, Diana Pessoa de Barros, José Luiz Fiorin, Elizabeth Harkot-de-la-Taille and Claude Zilberberg. The study begins by presenting the theoretical fundamentals of the semiotics of passion, followed by the analysis of the three short stories. Such analysis examines the way in which the feeling of pride and its spin-offs come about, as well as the way in which those of desire and its spin-offs accompany the transformations of each subjects state within the narratives. The examination is finalized by applying Zilberbergs concepts of tensivity and the flow of discourse, and by questioning the confrontation between the universe of social conventions and that of deceit, which permeates the objects of this study.
