MSSRVRD

Computes survival-movement, capture and recovery probabilities from multi-strata capture-recapture-recovery data.

JOLLYAGE

Computes estimates of survival and capture probability for 2-age class open population capture-recapture models.

TMSURVIV

Computes estimates of survival and capture probability and the proportion of transients in open population capture-recapture data.

Water Well Construction Reports

Water Well Constrution Reports entered online. 

DOSECOMP

Analyzes dose responses for two populations, using the PROBIT model and the abbreviated protocol as described by Link et al(1996).

MSSURVIV

Computes estimates of survival-movement and capture probability for open capture-recapture models.

CONTRAST

Compares estimates of survival (or any normally distributed parameter estimates).

SCATMAN

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

ESTIMATE

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

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 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

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.
