Frequency class

The frequency class of an object is a measure of its commonness. The frequency class of an object O, in a given set of objects, is defined as x iff the most common object in the set, M, is 2^x times as common as O. To wit:

Usage on the LifeWiki

Frequency classes given on the LifeWiki are computed relative to the block, using data from Catagolue's B3/S23/C1 census.

G1

For extremely rare objects, there might be enough occurrences for a large enough sample size in G1 but not C1. To calculate the frequency class using G1 data, take the standard formula and add 6.3; the number 6.3 was determined empirically. Make sure that the object being checked is one that doesn't get ignored in G1.
