The constant term in regression analysis is the value at which the regression line crosses the y-axis. The constant is also known as the y-intercept. That sounds simple enough, right? Mathematically, the regression constant really is that simple. However, the difficulties begin when you try to...
The degree to which the y -intercept ( Y -int) of the linear regression of maximal work output on exercise duration represented anaerobic capacity was determined in ten well-trained male cyclists [peak oxygen uptake ( \\\(\\\dot V{ext{O}}_{{ext{2peak}}} \\\) = 69.8 (SD 4.2) ml...

(This is also called linear regression.) In addition to the slope and y-intercept, the class can return the square of the correlation coefficient (R squared), the Durbin-Watson statistic, the mean squared error, sigma, the t statistics, the variance of the estimates of the slope and y-...
