To make it easier to practice counting, I will give an example of the data I have input in excel with n totaling 15, as can be seen in the table below: The formula for calculating multiple linear regression coefficients refers to the book written by Koutsoyiannis, which can be seen in the image below: Exercises for Calculating b0, b1, and b2Īfter we have compiled the specifications for the multiple linear regression model and know the calculation formula, we practice calculating the values of b 0, b 1, and b 2. This calculation is carried out for rice consumption (Y), income (X 1), and population (X 2) variables.Ĭalculating the actual data is reduced by the average value I use lowercase to distinguish from actual data. I chose to use a more straightforward and easier formula to calculate in the book.īut first, we need to calculate the difference between the actual data and the average value. I have read the econometrics book by Koutsoyiannis (1977). The bo (intercept) Coefficient can only be calculated if the coefficients b 1 and b 2 have been obtained. In calculating the estimated Coefficient of multiple linear regression, we need to calculate b 1 and b 2 first. Next, I compiled the specifications of the multiple linear regression model, which can be seen in the equation below: The Formula of Regression Coefficient Calculation Rice consumption is measured with million tons, income with million per capita, and population with million people. Based on the variables mentioned above, I want to know how income and population influence rice consumption in 15 countries. In the example case that I will discuss, it consists of: (a) rice consumption as the dependent variable (b) Income as the 1st independent variable and (c) Population as the 2nd independent variable. This time, the case example that I will use is multiple linear regression with two independent variables.

But for most people, the manual calculation method is quite difficult.īased on these conditions, on this occasion, I will discuss and provide a tutorial on how to calculate multiple linear regression coefficients easily. Completing these calculations requires an understanding of how to calculate using a mathematical equation formula.

It is essential to understand the calculation of the estimated Coefficient of multiple linear regression.
