summary.trial.fi: Summary of distance detection function model object

Description

Provides a brief summary of data and fitted detection probability model parameters, model selection criterion, and optionally abundance in the covered (sampled) region and its standard error.

Usage

# S3 method for trial.fi
summary(object, se = TRUE, N = TRUE, fittedmodel = NULL, ...)

Value

list of extracted and summarized objects

Arguments

object

a ddf model object

se

if TRUE, computes standard errors

N

if TRUE, computes abundance in covered (sampled) region

fittedmodel

full fitted model when called from trial or io

...

unspecified and unused arguments for S3 consistency

Details

The argument N is used to suppress computation of abundance and average detection probability in calls to summarize the ds and either io.fi or trial.fi for summaries of io and trial objects respectively which are composed of a ds model object and a mark-recapture model object. The corresponding print function is called to print the summary results.
