Subtract the "y" value of the first point from the "y" value of the second point to calculate the change in "y." Continuing with the previous example, (3,6) and (9,15) on the regression line, the calculated change in the "y" value is 15 – 6 = 9. Step 4 Divide the change ...
In thefield of finance, the regression formula is used to calculate the beta, which is used in the CAPM model todetermine the cost of equityin the company. The cost of equity is used in the equity research and to provide valuations of the company. Regression is also used in forecasting t...
