marked - Mark-Recapture Analysis for Survival and Abundance Estimation

Functions for fitting various models to capture-recapture data including mixed-effects Cormack-Jolly-Seber(CJS) and multistate models and the multi-variate state model structure for survival estimation and POPAN structured Jolly-Seber models for abundance estimation. There are also Hidden Markov model (HMM) implementations of CJS and multistate models with and without state uncertainty and a simulation capability for HMM models.

expQ2 - Non-negative vector * exp of rate matrix

Calculate `v'exp(Q)` by uniformisation or scaling and squaring, or exp(Q) by scaling and squaring. This is a duplicate of the `expQ` package written by Chris Sherlock hosted at "https://github.com/ChrisGSherlock/expQ" with changes made to pass R CRAN checks.

multAbund - Model Multivariate Abundance and Occurence Using the Dirichlet Process Prior

This package provides RJMCMC samplers to make Bayesian inference for Joint Species Distribution models (JSDM) using a Dirichlet Process clustering method. The DP clustering method allows species to be grouped into functional guilds for modeling between species associations in abundance or occurence values at surveyed sites.

agTrend.ssl - Aggregated Abundance Trends using GAMs

The package supplies a set of functions for stochastically imputing missing site-level abundance measurements so sites can be aggregated to regional abundance for trend estimation. This package is specifically intended for trend estimation for the NMFS Alaska Fisheries Science Center's assessment of Steller sea lion trends in Alaska and the U.S. west coast. Although the methodology is applicable to other applications, there are aspects of sea lion surveys hard coded into the analysis.
