R-Project regression with Wins as the dependent variable and all other numeric variables as independent variables.
•Is the overall fit of the model high or low? What tells you this?
•Is the model fit due to the number of variables? How can you tell?
•What are the most significant variables in your model? What information tellsyou this?
•Do you see anything surprising in the results? (Hint: Do the coefficient signs make sense?)
