WebMay 12, 2024 · Regression Line Equations. As we just learned, linear regression for two variables is based on a linear equation: Y ^ = a + ( b ∗ X) where a and b are constant numbers. What this means is that for every sample, the intercept (a) and the slope (b) will be the same for every score. The X score will change, and that affects Y (or predicted Y, or ... WebThis means that our regression equation accounts for some 40% of the variance in performance. This number is known as r-square. R-square thus indicates the accuracy of our regression model. A second way to compute r-square is simply squaring the correlation between the predictor and the outcome variable. WebApr 11, 2015 · 13th Apr, 2015.
