Unbalanced design for random effects. Suppose that the random effects model of Section 13.4 is to be estimated with a panel in which the groups have different numbers of observations. Let Ti be the number of observations in group i. a. Show that the pooled least squares estimator in (13-11) is unbiased and consistent despite this complication. b. Show that the estimator in (13-29) based on the pooled least squares estimator of (or, for that matter, any consistent estimator of) is a consistent estimator of 2 .
