Harmonic mean index
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. Geometric mean of a continuous function [ edit] WebCompute the Harmonic Mean p-Value Compute the Harmonic Mean p-Value Description The harmonic mean p-value (HMP) is defined as the inverse of the (possibly weighted) arithmetic mean of the inverse p-values. When the HMP is small (e.g. less than 0.05), it is approximately well-calibrated, meaning that it can be directly interpreted.
