#' Trend and Indices for Monitoring Data
#'
#' 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}
#' based
