Watterson estimator



 The introduction to this article provides insufficient context for those unfamiliar with the subject.
Please help improve the article with a good introductory style.

In population genetics, the Watterson estimator is a method for estimating θ = 4Neμ, where Ne is the effective population size and μ is the mutation rate of the population of interest (Watterson (1975)). The assumptions made are that there is a sample of n individuals from the population of interest, there are an infinitely many alleles possible, and that n \ll N_e.

The estimate of θ is

\theta = { K \over a_n },

where K is the number of segregating sites in the sample and

a_n = \sum^{n-1}_{i=1} {1 \over i}

is the (n − 1)th harmonic number.

This estimate is based on coalescent theory.
