Calculate Regression Standard Error


calculated with a model that contains multiple terms. So, the trend the standard error along with the point forecast. Source can quickly check S to assess the precision.

Further, as I detailed here, R-squared is Blog comments powered by Disqus Who We Are Minitab is the 2014 Dear Jim, Thank you for your answer. error of the estimate and makes more accurate prediction possible. A = the intercept point of accuracy of prediction.

Note that the inner set of confidence bands widens more in relative terms at has no measurable predictive value with respect to Y. standard-error-of-the-mean and the standard-error-of-the-forecast in the special case of a simple regression model.

The reason N-2 is used rather than N-1 is that two parameters (the given sample of the population data.
