In statistics, the regression line is used widely to determine the t-statistics.For example, there may be a very high correlation between the number of salespeople employed by a company, the number of stores they operate, and the revenue the business generates.

Regression is also used in forecasting the revenue and expense of the company it may be useful to do multiple regression analysis to determine how the alterations of the assumptions mentioned will impact the revenue or the expense in the future of the company.The cost of equity is used in the equity research and to provide valuations of the company. In the field of finance, the regression formula is used to calculate the beta, which is used in the CAPM model to determine the cost of equity in the company.The relevance and importance of the regression formula are given below: The relevance and the use of regression formula can be used in a variety of fields. The regression formula has one independent variable and has one dependent variable in the formula, and the value of one variable is derived with the help of the value of another variable. So the regression line can be defined as Y = a +bX which is Y = 3.81 + 0.09 * Xģ.81 is the intercept which can be defined as the value which remains constant irrespective of the changes in the independent variableĠ.09 in the equation is the slope of the linear regression, which defines how much of the variable is the dependent variable on the independent variable Explanation So the regression line can be defined as Y = a +bX which is Y = 1.97 + 0.66 * Xġ.97 is the intercept which can be defined as the value which remains constant irrespective of the changes in the independent variable.Ġ.66 in the equation is the slope of the linear regression, which defines how much of the variable is the dependent variable on the independent variable. Now, first, calculate the intercept and slope for the regression equation.

0.95 in the equation is the slope of the linear regression, which defines how much of the variable is the dependent variable on the independent variable.

1.5 is the intercept which can be defined as the value which remains constant irrespective of the changes in the independent variable.

x here is an independent variable, and y is the dependent variable which changes with the change in the value of x by a certain value.

So the regression line can be defined as Y = a +bX which is Y = 1.5 + 0.95 * X

Now, first calculate the intercept and slope for the regression equation.Ī (Intercept) is calculated using the formula given belowĪ = (((Σy) * (Σx 2)) – ((Σx) * (Σxy))) / n * (Σx 2) – (Σx) 2 We have all the values in the above table with n = 4. You need to calculate the linear regression line of the data set.įirst, calculate the square of x and product of x and y
