The regression line always goes through ____ The origin The point of averages The point of the maximum values The point of no return When calculating the standard error of the estimate in linear regression using sample with n observations, we first calculate the Sum of Squares Error (SsE) and then divide by and then i=1 ; n-2; take the square root of the result n Vi-y i=1 ; n-2; take the square root of the result Yi -- y)2; n-1; multiply by the square root of the result n (yi -- y,)2; n-2; use the result as the standard error of the estimate i=1
