rtrim-package

The TRIM model is used to estimate species populations based on frequent
(annual) counts at a varying collection of sites. The model is able to take
account of missing data by imputing prior to estimation of population totals.
The current package is a complete re-implementation of the <code>Delphi</code>
based

software developed at Statistics Netherlands by Jeroen Pannekoek.

The TRIM model is widely used for estimating growth and decline of
animal populations based on (possibly sparsely available) count data. The
current package is a reimplementation of the original TRIM software developed
at Statistics Netherlands by Jeroen Pannekoek. See
