WebThe goal of direct regression is to find the line of best fit that describes the relationship between X and Y. The equation for direct regression is Y = bX + a, where b is the slope of the line and a is the intercept. Reverse regression, also known as inverse regression, involves predicting the value of X based on the value of Y. WebThe Pearson correlation coefficient of x and y is the same, whether you compute pearson(x, y) or pearson(y, x). This suggests that doing a linear regression of y given x or x given y should be the same, but I don't think that's the case.
