In a regression line y a + bx x is

WebThe formula to determine the Least Squares Regression Line (LSRL) of Y on X is as follows: Y=a + bX + ɛ. Here, Y is the dependent variable. a is the Y-intercept. b is the slope of the … WebIt turns out that the line of best fit has the equation: y ^ = a + b x. where a = y ¯ − b x ¯ and b = Σ ( x − x ¯) ( y − y ¯) Σ ( x − x ¯) 2. The sample means of the x values and the y values are x ¯ and y ¯, respectively. The best fit line always passes through the point ( x ¯, y ¯).
