RRS
RRS is defined as the ratio of offspring per hatchery parent spawning naturally to offspring per wild (natural spawned) parent
spawning naturally (Hinrichsen 2003, Araki et al. 2008). Computer programs written in the statistical computing language R
are provided to estimate RRS and the precision of the estimate. One of the programs is designed to correct for bias in the
estimate of RRS when the data contain a large number of sampling zeros. The other two programs provide guidance on sample size
and statistical power when the null hypothesis is RRS is equal to one.
Documents included in the download provide background information, instructions on how to run the programs, and sample data.

Estimating Brood and Nest Survival
|
This zip file contains Windows programs for the iterative Mayfields (MAYITER.EXE) and maximum likelihood estimation (BROODMLE.EXE) of survival rates as used for the papers below. When the programs are started the format for the data is described and two example sets of data MAYITER.DAT and BROODMLE.DAT are also in this zip file.

Capture-Recapture Routines for the "Handbook of Capture-Recapture Analysis"
|
The software routines referred to in Chapter 9 of Handbook for Capture-Recapture Analysis are now an official package for R.
These routines are available from here.
There are 2 ways to install:
Download the "windows binary" zip file from CRAN, then from within R, choose
"Packages" - "Install from local zip file". When prompted, navigate to the downloaded zip and select okay.
Start R. Assuming you have a live internet connection,
select 'Packages' – 'Install packages' from the R menus. A dialog box asking you to choose a nearby CRAN site may
appear. If so, select one. Another dialog box should appear listing all the packages available for R. Scroll down
to 'mra' (list is alphabetical, and long), select 'mra' and click okay. The binary zip will then download and
install automatically.
Important: After installing MRA using either of the above methods, you must load the library prior to accessing the routines.
Load the library by issuing the command 'library(mra)" at the R command prompt. If you do not take this step, R
will not be able to find the routines. After installation and loading, type "help(mra)" to view detailed documentation.

S-Draw : GRTS for the Average Joe
|
S-Draw is a program for drawing generalized random tessellation stratified
(GRTS) samples and other types of probability samples. S-Draw accepts
simple inputs such as population and sample size, or complex enumeration
sampling frames containing UTM coordinates, ID's, and weights. A complete
help file is included.
Please contact Trent McDonald at WEST, Inc., for information on S-Draw.
