WebThe third column indicates the number of OTUs with only one indivdiual, the fourth the number of OTUs with two individuals, etc. Good’s coverage is then calculated using the values found in the subsequent columns. For demonstration we will calculate Good’s coverage for an OTU definition of 0.03: C = 1 − 75 98 = 0.23 C = 1 − 75 98 = 0.23. WebAbstract. A generalized form of Good's estimator (Good, 1953) is proposed to estimate the coverage of a random sample from an unknown multinomial distribution. Some properties of the proposed estimator are derived. This generalized estimator retains all good properties Of Good's estimator and has smaller bias if each cell probability is less ... WebAug 19, 2013 · The coverage and its deficit are the aspects of undetected species that can be accurately estimated by sample data (Good 1953; Lande, DeVries & Walla 2000).

Webwhere δkj (n) = I{Xk(n)=j}.Then1−Qn is called the sample coverage which is the sum of the probabilities of the observed species. Good (1953) proposed the estimator Qˆ n = F1(n) n (1.2) for Qn. The Good estimator Qˆ n has many applications such as Shakespeare’s general vocabulary and authorship of a poem [Efron and Thisted (1976), Thisted ... 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)
