This means from the given data we calculate the distance from each data point to the regression line, square it, and the sum of all of the squared errors together. The OLS method seeks to minimize the sum of the squared residuals. The OLS method is used to estimate β0 and β1. This is a line where y is the dependent variable we want to predict, x is the independent variable, and β0 and β1 are the coefficients that we need to estimate. The simple linear regression is a model with a single regressor (independent variable) x that has a relationship with a response (dependent or target) y that is a Step 2: Rearrange the linear regression equation using algebra to fit the regression slope. For this sample question, the linear regression equation is: y’ 65.14 +. If you don’t know how, see: Find a linear regression equation. This post will help you to understand how simple linear regression works step-by-step. Step 1: Find the linear regression equation (you may have already been given it in the question). If you are new to linear regression, read this article for getting a clear idea about the implementation of simple linear regression. If we choose the parameters and in the simple linear regression model so as to minimize the sum of squares of the error term, we will have the so.
