In recent years, fair allocation of resources or fixed costs in DEA have been noticed by researches, in which the main objective is unchanging efficiency of decision making units, In which the main purpose is to not change the efficiency of decision-making units before and after the allocation of costs. On the other hand, all studies have been due to the fraction-scale data, and any special att...

normal 0 false false false en-us x-none fa background: the angular dependency of response for tld cards may cause deviation  from its true value on the results of environmental dosimetry, since tlds may  be exposed to radiation at different angles of incidence from the surrounding area. objective: a 3d setting of tld cards has been calibrated isotropically in a standard  radiation field to eval...

It is known that in general, statistical analysis of interval data is an NP-hard problem: even computing the variance of interval data is, in general, NP-hard. Until now, only one case was known for which a feasible algorithm can compute the variance of interval data: the case when all the measurements are accurate enough – so that even after the measurement, we can distinguish between differen...

The area under the receiver operating characteristic curve is the most commonly used measure of the ability of a biomarker to distinguish between two populations. Some markers are subject to substantial measurement error. Under normality assumptions, the authors develop a confidence interval procedure for the area under the receiver operating characteristic curve that adjusts for measurement er...
