Part 1 of assumption 2
Properties of the CRM estimator

Gauss Markov Theorem
Subject to assumption one and tow, the CRM estimator has minimum variance in the class of conditionally unbiased and linear estimators (BLUE)
Efficiency of Normal CRM
beta hat has miniimum variance in the class of conditionally unbiased estimators
It attains the Cramer Rao bound for the conditional likelihood model
