Is there a textbook you'd recommend to get the basics of regression right (with the math involved)? In the regression output for Minitab statistical software, you can find S in the Summary of Model section, right next to R-squared. Sign in to add this to Watch Later Add to Loading playlists...

Linear regression is the technique for estimating how one variable of interest (the dependent variable) is affected by changes in another variable (the independent variable). All rights reserved. Suppose our requirement is that the predictions must be within +/- 5% of the actual value. Your cache administrator is webmaster. Source
For the BMI example, about 95% of the observations should fall within plus/minus 7% of the fitted line, which is a close match for the prediction interval. Why I Like the Standard Error of the Regression (S) In many cases, I prefer the standard error of the regression over R-squared. And, if I need precise predictions, I can quickly check S to assess the precision.

If you don't know how to enter data into a list, see:TI-83 Scatter Plot.) Step 2: Press STAT, scroll right to TESTS and then select E:LinRegTTest Step 3: Type in the I did ask around Minitab to see what currently used textbooks would be recommended. Thanks for the question! Standard Error Of Regression Slope Calculator Regressions differing in accuracy of prediction.

However, you can use the output to find it with a simple division. At a glance, we can see that our model needs to be more precise.

http://blog.minitab.com/blog/adventures-in-statistics/multiple-regession-analysis-use-adjusted-r-squared-and-predicted-r-squared-to-include-the-correct-number-of-variables I bet your predicted R-squared is extremely low.
