Conduct all tests at a = 0.05 significance level. Q.1. Prediction Markets: In many sports betting lines (point spreads and Over/Under totals) are set for games/matches These can be used to monitor how well the groups who set the betting lines perform. We consider a models based on all Women's National Basketball Association (WNBA) games over the 2010-2019 regular seasons. Consider these variables teamSprd - The number of points the team is "expected" to win by (positive means to win, negative to lose) team Win - 1 if the team won the game, 0 if it lost Consider a logistic regression model, relating the probability the team wins (team Win=1) as a function of teamSprd. The result of the logistic regression model is given below. modi summary (mod1) coefficients : Estimate Std.
