optimal.prob: Returns an estimate of the fundamental biodiversity number

Description

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

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()
