wlrm_transformed: function for species richness estimation

Description

This function implements the transformed version of the species richness estimation procedure outlined in Rocchetti, Bunge and Bohning (2011).

Usage

wlrm_transformed(data, print=TRUE, plot=FALSE, answers=FALSE, cutoff=NA)

Arguments

data
The sample frequency count table for the population of interest. See breakaway for details.
print
Logical: whether the results should be printed to screen.
plot
Logical: whether the data and model fit should be plotted.
answers
Logical: whether the function should return an argument.
cutoff
The maximum frequency count to use for prediction. Defaults to maximal.

Value

name
The ``name'' of the model.
para
Estimated model parameters and standard errors.
est
The estimate of total (observed plus unobserved) diversity.
seest
The standard error in the diversity estimate.
full
The chosen linear model for frequency ratios.
ci
An asymmetric 95% confidence interval for diversity.
