Regression Coefficient
While analysing regression in two related series, we calculate their regression coefficients also. There are two regression coefficients like two regression equations. Regression equation is that ratio which tells that with a changes of 1 in one series what will be an average changes in other series. In reality it is an algebraic measurement of the slope of regression line, means it decides the slope of regression line.
