چکیده
Recently, Chambers et al. (Journal of Economic Theory 70 (1996) 407}419; Working Paper, Southern Illinois University, Carbondale, 1996) have developed the concept of directional distance to measure technical e$ciency. However, there is no guarantee that such a measure must intersect the e$cient subset (also called strong e$cient subset) de"ned by Koopmans (Activity Analysis of Production and Allocation, 1951, Vol. 36, pp. 27}56), that is primarily the Pareto e$cient subset. So, we develop a framework for measuring e$ciency in the full input/output space. Following FaK re and Lovell (Journal of Economic Theory 19 (1978) 150}162), we introduce a graph-type extension of the Russell measure. Moreover, we show that our new measure can be computed by using linear programming. ( 2000 Elsevier Science B.V. All rights reserved.

We introduce trading rules which are selected by an arti cially intelligent agent who learns from experience an Arti cial Technical Analyst. It is shown that these rules can lead to the recognition of subtle regularities in return processes whilst reducing data-mining problems inherent in simple rules proposed as model evaluation devices.

(1) B is k-isogenous to an abelian subvariety of A. (2) fB|fA in Q[T ]. In particular, A is k-isogenous to B if and only if fA = fB. Moreover, A is k-simple if and only if fA is a power of an irreducible polynomial in Q[T ]. Recall that the roots of fA in C are “Weil q-integers”: algebraic integers whose images in C all have absolute value q. By Theorem 1.1 to describe the isogeny classes of ab...
متن کاملThe Extended Low Hierarchy Is an In niteHierarchy 1
Balc azar, Book, and Sch oning introduced the extended low hierarchy based on the levels of the polynomial-time hierarchy as follows: for k 1, level k of the extended low hierarchy is the set ELP; k = fA j Pk (A) Pk 1(A SAT)g. Allender and Hemachandra and Long and Sheu introduced re nements of the extended low hierarchy based on the and -levels, respectively, of the polynomial-time hierarchy: ...
متن کاملMeasurement e#ciency and productivity in SAS/OR
This paper explores the use of the optimisation procedures in SAS/OR software with application to the measurement of e#ciency and productivity of decision-making units (DMUs) using data envelopment analysis (DEA) techniques. DEA was originally introduced by Charnes et al. [J. Oper. Res. 2 (1978) 429] is a linear programming method for assessing the e#ciency and productivity of DMUs. Over the la...
