trim.var

(usually the <code>$study.area.total</code> element
of a returned <code>dsm</code> bootstrap object.

untrimmed.bootstraps

the value of <code>coef</code> used to calculate the outliers
see <code><a rd-options="" href="/link/boxplot?package=dsm&version=2.3.1" data-mini-rdoc="dsm::boxplot">boxplot</a></code>.

boxplot.coef

Trim the variance estimates from the bootstrap. This is defined as the percentage defined as amount necessary to bring median and trimmed mean within 8

Density surface modelling of line transect data. A Generalized
Additive Model-based approach is used to calculate spatially-explicit estimates
of animal abundance from distance sampling (also presence/absence and strip
transect) data. Several utility functions are provided for model checking,
plotting and variance estimation.
