QLIM Procedure

The following new features have been added to the QLIM procedure:

• The TE1 and TE2 options output technical efficiency measures for each producer in stochastic frontier models as suggested by Battese and Coelli (1988) and Jondrow at al. (1982).

• The WEIGHT statement is now supported. A WEIGHT statement identifies a variable to supply weights for each observation in the dataset. By default, the weights are normalized so that they add up to the sample size. If the NONORMALIZE option is used, the actual weights are used without normalization.
