英文文献：Testing For Input And Output Separability In Nebraska Agriculture Sector
英文文献作者：Shaik, Saleem,Helmers, Glenn A.
英文文献摘要：
The existence of Weak Separability aggregates of inputs and outputs is tested using a Translog production and input requirement function for the Nebraska Agricultural sector for 1936-1994. A separability test was performed only after testing time series properties by comparing the null hypothesis of stationarity against the alternative of unit roots.
