Ordinary least squares (OLS) regression is a method that allows us to find a line that best describes the relationship between one or more predictor variables and a response variable. This method allows us to find the following equation: ŷ = b0 + b1x. where: ŷ: The estimated response value. b0: The intercept of the regression line.OLS estimation is a statistical method used to estimate the parameters of a linear regression model. It involves finding the line of best fit that minimizes the sum of the squared residuals between the predicted and actual values. The OLS estimator is unbiased, consistent, and efficient, making it a popular choice for estimating linear models.Support Information.
