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

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

Computes the power of between-model likelihood ratio tests.

MULT

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

RELEASE

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

CAPTURE

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

SURVIV

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

MAYFIELD

Computes estimates of daily survival rate for nest visitation data.

CAPQUOTA

Computes expected coefficients of variation of survival and capture probability for use in the design of capture-recapture-resighting experiments.

SPECRICH

Computes "species richness" or total number of species from emperical species abundance distribution data.
