WebMetrics that are inversely proportional to time (speedup, IPC) should be averaged using the harmonic mean. The geometric mean can be derived from the generalized mean as its limit as goes to zero. Similarly, this is possible for the weighted geometric mean.

Unweighted, or "elementary", price indices only compare prices of a single type of good between two periods. They do not make any use of quantities or expenditure weights. They are called "elementary" because they are often used at the lower levels of aggregation for more comprehensive price indices. In such a case, they are not indices but merely an intermediate stage in the calculation of an index. At these lower levels, it is argued that weighting is not nece…
WebIn mathematics, the geometric–harmonic mean M(x, y) of two positive real numbers x and y is defined as follows: we form the geometric mean of g 0 = x and h 0 = y and call it g 1, i.e. g 1 is the square root of xy.We also form the harmonic mean of x and y and call it h 1, i.e. h 1 is the reciprocal of the arithmetic mean of the reciprocals of x and y.These may be done … miles wa real estateWebMay 21, 2024 · The harmonic mean of the intensity-weighted size distribution, on the other hand, agrees with the z -average within 2% on average.
