Software

Code is generally posted as documentation is completed, except as noted. Please contact me if you don't want to wait for the final documentation.

Model Assessment

ParetoEvolve       download       DISCUSSION BOARD

UNDER DEVELOPMENT. A general purpose evolutionary computation multi-criteria optimizer, written in C. Requires user modification of header files and recompiling. (created with Marianne Turley and Rie Komuro)

MC Modeller       forthcoming

A graphic user interface for generating a model's Pareto Frontier using either ParetoEvolve (without the hassle of editing and recompiling) or Monte Carlo simulation. The model is limited to at most 20 assessment criteria and 20 parameters. (provided by Abran Steele-Feldman)

Wildlife & Natural Resource Software

Visual MS-SURVIV: a graphic user interface for MS-SURVIV       forthcoming

A kinder interface to the MS-SURVIV software for fitting multi-state mark recapture models with either 1^st (memoryless) or 2^nd order (memory) Markovian movement. Available with incomplete documentation - contact me. (provided by Abran Steele-Feldman)

Double Observer Distance Estimation       forthcoming

Functions for fitting the distance sampling models of Becker and Quang (JABES in press).Available with incomplete documentation - contact me.

Variance estimators for non-replicated Systematic Samples       R functions    Excel macros

Estimators V2, V3, V4, and V5 from Wolter, K. M. 1984. An investigation of some estimators of variance for systematic sampling. Journal of the American Statistical Association 79(388): 781-790.

Single strata patch occupancy model       forthcoming

Estimation functions for both simple random sample design (standard model) and sequential sampling design.

SPAM Statistical Program for Analyzing Mixtures

Software for fitting finite mixtures of discrete distributions. Specifically developed for genetic stock identification or mixed stock analysis in fisheries, but fairly flexible (haploid or diploid markers, etc.). (Alaska Department of Fish and Game's Gene Conservation Laboratory)

R Functions

Algorithm Comparison       forthcoming

Functions for assessing performance of evolutionary computation algorithms using on compositional data analysis methods.

Double Observer Distance Estimation      forthcoming

functions for fitting the distance sampling detection models of Becker and Quang (JABES in press). Peak detection can be less than 100% and occur off transect. Internally documented, example scripts included, manual forthcoming. Available with incomplete documentation - contact me.

Variance estimators for non-replicated Systematic Samples       R functions    Excel macros

Estimators V2, V3, V4, and V5 from Wolter, K. M. 1984. An investigation of some estimators of variance for systematic sampling. Journal of the American Statistical Association 79(388): 781-790.

Single strata patch occupancy model       forthcoming

Estimation functions for both simple random sample design (standard model) and sequential sampling design.

Compositional Data Analysis      download

Various functions for manipulating compositional data: closure, compositional addition and differences, ternary and exploded tetrahedron plots, etc. Internally documented.
