SCATMAN SCATMAN

Tests the hypothesis of prey-selectivity based on random samples of predator scats.

ESTIMATE ESTIMATE

Estimates fatalities using raw counts of wildlife fatalities, trial experiments for carcass detection probability and persistence time.

SPECtrum Processing Routines (SPECPR) SPECtrum Processing Routines (SPECPR)

SPECPR is an Interactive One Dimensional Array Processing System, with the tools needed for reflectance spectroscopy analysis. It also has tools to do a lot of other tasks and analyses of x,y paried data.

SeisRisk III SeisRisk III

Seisrisk III is the last published version of a series of programs used to produce probabilistic earthquake ground motion hazard maps for the United States from 1972 to 1992.

Slick Package Slick Package

The slick package uses fault slip data (either field observations or from focal mechamism) to find the stress tensor that best explains the observations. Inputs are the orientation and slip direction of a set of fault planes.

BAND2: A Computer Program for Sample Size Computations for Banding Studies BAND2: A Computer Program for Sample Size Computations for Banding Studies

Computes the number of animals that must be banded in order to achieve a specified level of precision for survival rates estimated using band recovery models.

POWER POWER

Computes the power of between-model likelihood ratio tests.

MULT MULT

Computes estimates of survival and temporary emigration under the "Open Robust Design".

RELEASE RELEASE

Computes estimates of survival and capture probability for capture-recapture experiments on open animal populations.

CAPTURE CAPTURE

Computes estimates of capture probability and population size for "closed" population capture-recapture data.

SURVIV SURVIV

Computes estimates of survival (or any model parameter) with multinomially distributed data.

MAYFIELD MAYFIELD

Computes estimates of daily survival rate for nest visitation data.
