The Elo[ a] rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess or esports. It is named after its creator Arpad Elo, a Hungarian-American physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, [ 1] but is also used as ...
The rock mass rating ( RMR) is a geomechanical classification system for rocks, developed by Z. T. Bieniawski between 1972 and 1973. [ 1] Since then it has undergone multiple modifications out of which, RMR89 [ 1] is commonly used. Recently RMR14 [ 2] has been proposed to improve the RMR performance by incorporating new experiences from tunnel ...
The rating for all-electric mode (left) is expressed in miles per gallon gasoline equivalent (mpg). Miles per gallon gasoline equivalent ( MPGe or MPGge) is a measure of the average distance traveled per unit of energy consumed. MPGe is used by the United States Environmental Protection Agency (EPA) to compare energy consumption of alternative ...
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, 2016, 2017, and 2023 versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid drivetrains (Chevrolet ...
For example, if both p -values are around 0.10, or if one is around 0.04 and one is around 0.25, the meta-analysis p -value is around 0.05. In statistics, Fisher's method, [1] [2] also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald ...
The gross combined weight rating or gross combination weight rating (GCWR), also referred to as the gross combination mass (GCM), gross train weight (GTW), is the maximum allowable combined mass of a road vehicle, the passengers and cargo in the tow vehicle, plus the mass of the trailer and cargo in the trailer.
For example, opponents of the 2016 New England Patriots had a combined record of 111–142–3 (a win percentage of 0.439, the SOS), and Patriots' wins came against teams with a combined record of 93–129–2 (a win percentage of 0.420, the SOV).
The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
