Regression Formula Y On X. The distance of a line above or below the origin and parameter b tells about the slope of the line i e. And x and y are the mean value.
The formula for linear regression equation is given by. This is used to describe the variations in the value y from the given changes in the values of x. Now let us see the formula to find the value of the regression coefficient.
A and b can be computed by the following formulas.
This is used to describe the variations in the value y from the given changes in the values of x. Regression line formula y a b x y 59 98 0 59 x y 105 15 105 therefore as per the regression level the glucose level of a 77 year old person is predicted to be 105mg dl. B the slope of the regression line a the intercept point of the regression line and the y axis. Y a bx.
