![]() Step 1: Put the value of X in the computed regression equation. Step 3: Put both values in the regression equation. Now, use this data in the intercept equation. Putting these values in the equation, we have ī = / 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.
