How To Interpret R-squared in Regression Analysis

WebDec 6, 2024 · Take a look at the equation and notice that when R-squared equals 0, both the numerator and denominator equal 1, producing a VIF of 1. This is the lowest possible VIF and it indicates absolutely no multicollinearity. As R-squared increases, the denominator decreases, causing the VIFs to increase. WebHow do you interpret a coefficient of determination, r2, equal to 0.06? Choose the correct answer below. O A.

WebR 2 represents the proportion of total variability of the y -value that is accounted for by the independent variable x. For the specific case when there is only one independent variable X (i.e., simple linear regression), one can show that R 2 = r 2, where r is correlation coefficient between X and Y. Example 9-6: Student height and weight ( R 2 ) WebR2 only measures how well a line approximates points on a graph. It is NOT a probability value. How likely a model is correct depends on many things and is the subject of hypothesis testing (covered in future videos).
