procedure. If we had polled different residents, we might have gotten a different average social networking hours. In general, the characteristics of the observed distribution (mean, median, variance, range, IQR, etc.), change from sample to sample, and may never exactly match the population quantities. To visualize properties of sampling distributions, we will use the sampling lab, and the very nice website at: http://onlinestatbook.com/stat_sim/sampling_dist/index.html Statistical Inference: A body of

STOCHASTIC FRONTIER ANALYSIS 1 MOTIVATION • Usual textbook presentations treat producers as successful optimizers. They maximize production, minimize cost, and maximize profits. • Conventional econometric techniques build on this paradigm to estimate production/cost/profit function parameters using regression techniques where deviations of observed choices from optimal ones are modeled as statistical noise. • However though every producer may attempt to optimize, not all of them may succeed
