Often X is a variable which logically can never go to zero, or even close to it, given the way it is defined.

So now I need to find the confidance interval of a. s actually represents the standard error of the residuals, not the standard error of the slope. But, the sigma values of estimated trends are different. Standard Error Of Estimate Calculator I think it should answer your questions.

S is known both as the standard error of the regression and as the standard error of the estimate. You interpret S the same way for multiple regression as for simple regression. Learn more You're viewing YouTube in Greek. navigate here Continuous Variables 8.
