查询词典 weighted function

A new pricing approach to real option is thus proposed to transform the forecast intervals evaluated by experts into some normal fuzzy numbers with the lattice closeness degree introduced to construct weighted vectors.

First, a specialist in Emergency medical review the 1,281 charts during June 24-July 8, 2004 to decide syndrome group of each patient, and using it as the golden standard. This study collected CC, ICD-9 code, body temperature, and epidemiological data of 126,675 emergency department patients in five hospitals in Taipei during Oct. 1, 2005-Feb. 14, 2007 to set up Poisson regression for counts time series model and use cumulative sum and exponential weighted moving average for alerting.
