Suppose a dependent variable depends only on a constant (Bo) so your model is: yi = β0 + ui where ui is an error term. Please derive the OLS estimator for β0. (In order to derive this estimator, you will need to set up a minimization problem and use calculus to find the estimator that minimizes the sum of squared residuals.)

Long division setup showing an incomplete calculation. 12 is in the divisor, 6839 is in the dividend, and 5 hundreds and 6 tens is written in the quotient. 6000 is subtracted from 6839 to give 839. an unknown value represented by a box is being subtracted from 839. what number should be placed in the box to complete the division calculation?
