Calculate Good’s coverage estimator.
Good’s coverage estimator \(C\) is an estimation of the proportion of the population represented in the sample. It is defined as
\[C = 1 - \frac{F_1}{N}\]where \(F_1\) is the number of taxa observed only once (i.e., singletons) and \(N\) is the total number of individuals.
- Parameters:
- counts1-D array_like, int
Vector of counts.
- Returns:
- double
