WebWhen used for method comparison, linear regression analysis can determine statistics such as correlation coefficient, slope, intercept, and confidence intervals. The correlation coefficient measures the strength and direction of the relationship of two variables. A Pearson correlation (r) of 1 suggests a perfect positive linear relationship. WebRegression analysis also falls short in certain cases which are more difficult to model. For instance, in football, 3 or 7 points are typically scored at a time, so bets involving a final score frequently include combinations of these two numbers. However, a simple linear regression will not accurately model this. Statistical anomalies
