![]() It will be easy to make a table and find the necessary values through it. Given these then pairs of (X, Y) values X To clear your concept, read the solved example below. The ͞ y and ͞ x represent the mean of y and x respectively.Īfter finding both values, all you have to do is put them in the sample equation. To find the y-intercept, use the given formula. In this formula, the numerator is the covariance of x and y and the denominator is the variance of x. The basic and easiest one is the one written below. ![]() There are two main values that you have to calculate to make the regression equation y-intercept(a) and slope(b). How to calculate the regression equation? Now let’s move on to the computation of this equation.
