A Measure of Production Performance
展示如何利用M分位数回归方法构建生产绩效指标，实现企业间有意义的比较，并用1978-1987年澳大利亚牧区农场调查数据验证。
Abstract Suppose there are data available on the value of business output, as measured by a single variable y and the values of the corresponding inputs x, with the relationship between y and x determined by an appropriately chosen production function. It is shown how M-quantile regression methods can be used to construct a performance measure that allows a meaningful comparison of the production performance of the businesses. The method is illustrated using survey data collected from farm businesses in the pastoral zone of New South Wales and southern Queensland between 1978 and 1987.
