Efficiency Measurement with the Weibull Stochastic Frontier*
提出用威布尔分布建模技术效率，该分布有形状和尺度参数，可作为伽马分布的实用替代。用人工数据和西班牙奶牛场面板数据演示方法。
Abstract In this paper we consider the Weibull distribution as a model for technical efficiency. The distribution has a shape and scale parameter like the gamma distribution and can be a reasonable competitor in practice. The techniques are illustrated using artificial data as well as a panel of Spanish dairy farms.
