Quizplus · Accepted Answer

$\hat \beta$ = ( $X ^ { \prime }$ X)^-¹ $X ^ { \prime }$ ^U$\hat \beta$ is the least squares estimator of the population parameter $\beta$. It is calculated by multiplying the inverse of the covariance matrix of the independent variables by the transpose of the independent variables and then multiplying the result by the dependent variable.
