WebGood's u = the index of frequency coverage described by Good (1953); the same equation is used during subsampling trials to see whether the quorum has been achieved, but this value pertains to the entire data set; subsampled richness = the geometric mean number of taxa found in subsamples (as generated either by SQS or rarefaction) WebThe coverage of a random sample from a multinomial population is defined to be the sum of the probabilities of the observed classes. The problem is to estimate the coverage of a random sample given only the number of classes observed exactly once, twice, etc. This problem is related to the problem of estimating the number of classes in the population. …
