The general regression model with n observations and k explanators, the first of which is a constant unit vector whose coefficient is the regression intercept, is where y is an n × 1 vector of dependent variable observations, each column of the n × k matrix X is a vector of observations on one of the k explanators, is a k × 1 vector of true coefficients, and e is an n × 1 vector of the true underlying errors. The ordinary least squares estimator for is WebThe principle underlying least squares regression is that the sum of the squares of the errors is minimized. We can use calculus to find equations for the parameters β0 and β1 that …
