[2]: 188 For example: if all y values are constant, the estimator with unknown population size will give the correct result, while the one with known population size will have some variability. Also, when the sample size itself is random (e.g.: in Poisson sampling ), the version with unknown population mean is considered more stable.
Wide area multilateration (WAM) is a cooperative aircraft surveillance technology based on the same time difference of arrival principle that is used on an airport surface. . WAM is a technique where several ground receiving stations listen to signals transmitted from an aircraft; then the aircraft's location is mathematically calculated -- typically in two dimensions, with the aircraft ...
Some other universities, such as the University of Melbourne, University of New South Wales, University of Sydney, and University of Wollongong [68] use a Weighted Average Mark (WAM) for the same purpose as a GPA. The WAM is based on the raw percentage grades, or marks, achieved by the student, rather than grade points such as High Distinction ...

Pseudo-range multilateration, often simply multilateration (MLAT) when in context, is a technique for determining the position of an unknown point, such as a vehicle, based on measurement of biased times of flight (TOFs) of energy waves traveling between the vehicle and multiple stations at known locations.
