Testing for the Monotone Likelihood Ratio Assumption
单调似然比假设的检验
Although monotonicity of the likelihood ratio for conditioned densities is a common technical assumption in economic models, empirical tests for its plausibility do not appear to have been conducted. This article develops such a test based on the theory of order-restricted inference that is robust with respect to the correlation structure of the distributions being compared. The test is applied to study the technology revealed by agricultural production experiments. For the…
