Returns an estimate of the fundamental biodiversity number

Returns a maximum likelihood estimate for the fundamental biodiversity number $\theta$ (function optimal.theta()) or the probability of mutation (function optimal.prob()) and optionally return information about the likely error

Keywords
math
Usage
optimal.prob(x,  interval=NULL, N=NULL, like=NULL, ...)
optimal.theta(x, interval=NULL, N=NULL, like=NULL, ...)
Arguments
x
Ecosystem vector or species count table
interval
Bracketing interval for probability of mutation to be passed to the optimization routine (here optimize()). Default of NULL means to use a wide interval. Note that this argument is interpreted as an interval of
N
Integer; the number of parametric resampled estimates to give. Default of NULL means to return just the maximum likelihood estimate
like
Units of likelihood to calculate credible interval. Edwards recommends using 2
...
Further arguments passed to optimize()
Note

The fundamental biodiversity parameter $\theta$ is $2\nu J$, where $\nu$ is the probability of mutation (ie, as estimated by optimal.prob()), and $J$ is the size of the ecosystem.

For the general case of dispersal limitation, see functions etienne() and optimal.params().
