OBJECTIVE To create patient-based disability weights for individual injury diagnosis codes and nature-of-injury classifications, for use, as an alternative to panel-based weights, in studies on the burden of disease. METHODS Self-reported data based on the EQ-5D standardized measure of health status were collected from 29 770 participants in the Injury-VIBES injury cohort study, which covered...

We used our extension of the kernel score test to family data to analyze real and simulated baseline systolic blood pressure in extended pedigrees. We compared the power for different kernels and for different weightings of genetic markers. Moreover, we compared the power of rare and common markers with 3 strategies for joint testing and on marker panels with different densities. Marker weights...

This study questions a common practice of using item weights for construct validity tests in the application of formative measurement. The practice does not confirm to the theoretical formation of formative constructs. A Monte Carlo simulation analysis is conducted to examine the practice. The results clearly demonstrate that item weights do not reflect the true design of the focal formative co...

Data envelopment analysis (DEA) calculates the relative efficiency of homogenous decision-making units (DMUs) with multiple inputs and outputs. Classic DEA models usually suffer from several issues such as: discrimination power, variable weights of inputs/outputs, inaccurate efficiency estimation for small number of DMUs, incapability in working with zero and negative data, and not having exter...

Fast parallel algorithms are given for the longest common subsequence problem and the string editing problem with bounded weights. In the COMMON PRAM model, the algorithm for the longest common subse-quence problem takes time O(log m), where m is the length of the shorter string, while the algorithm for the string editing problem with bounded weights takes time O(max(log m; log n= log log n)), ...

a camel research station was established in 1990 at the central desert land of iran named kavir-e-loot, to evaluate productivity performance of one humped camel. the data consisted of birth weights (bw), three (w3), six (w6), nine (w9) months and yearling (w12) body weight of animals and the pedigree was registered during a period of 14 years since 1991 to 2004. the body weight traits of birth,...

  A data envelopment analysis (DEA) method can be regarded as a useful management tool to evaluate decision making units (DMUs) using multiple inputs and outputs. In some cases, we face with imprecise inputs and outputs, such as fuzzy or interval data, so the efficiency of DMUs will not be exact. Most researchers have been interested in getting efficiency and ranking DMUs recently. Models of th...
