KTRLine: Kendall-Theil Robust Line - Software page KTRLine: Kendall-Theil Robust Line - Software page

Overview The Kendall-Theil Robust Line software (KTRLine—version 1.0) is a Visual Basic program that may be used with the Microsoft Windows operating system to calculate parameters for robust, nonparametric estimates of linear-regression coefficients between two continuous variables.

VBVenn: Visual Basic Venn diagram - Software page VBVenn: Visual Basic Venn diagram - Software page

Overview VBVenn is a Visual Basic program that calculates the size and position of two circles to construct a quantitative Venn diagram. It is a simple one-form program with a fairly intuitive user interface.

JOLLY JOLLY

Computes estimates of survival and capture probability for 1-age class open population capture-recapture models.

ZONECONC ZONECONC

ZONECONC is a postprocessing program that tabulates concentration statistics from concentration data generated by MODFLOW-GWT.

MSSRVMIS MSSRVMIS

Computes estimates of survival and capture probability adjusted for missclassification.

Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm is a Java application designed to display and analyze seismic waveforms in real-time.

Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm can connect to and read from a variety of different static and dynamics data sources, including Earthworm waveservers, IRIS DMCs, SEED and SAC files, and simple ASCII. Swarm has both time- and frequency-domain analysis tools, along with a simple but powerful mapping platfrom.

CountRemoval CountRemoval

A removal model for estimating detection probabilities from point count surveys.

VolatileCalc VolatileCalc

VolatileCalc calculates H 2O-CO 2-melt equilibrium for the rhyolite and basalt systems.

ORDSURVIV ORDSURVIV

Computes estimates of survival and recovery rates for band-recovery data with additional models for estimating reporting rate.

PTCOUNT PTCOUNT
