Web4.5 The Sampling Distribution of the OLS Estimator. Because \(\hat{\beta}_0\) and \(\hat{\beta}_1\) are computed from a sample, the estimators themselves are random variables with a probability distribution — the so-called sampling distribution of the estimators — which describes the values they could take on over different samples. … WebWe define the true population model as: Y i = 1 + 2X i + W i + u i 1 = 2 & = 1 set obs 100 gen w = rnormal() gen x = w + rnormal() gen y = 1 + 2*x + w + rnormal() ...
