Once you have fit a linear model using regression analysis, ANOVA, or design of experiments (DOE), you ought to decide how well the model fits the information. To assist you, Minitab software that is statistical a number of goodness-of-fit data. On this page, we’ll explore the R-squared (R 2 ) statistic, a few of its restrictions, and unearth some shocks as you go along. By way of example, low values that are r-squared not necessarily bad and high R-squared values are not necessarily good!
What exactly is Goodness-of-Fit for a Linear Model?
Linear regression determines an equation that minimizes the length between your fitted line and all sorts of associated with information points. Read more “Regression Analysis: How Can I Interpret R-squared and Gauge The Goodness-of-Fit?”
