  • Data Cloning I: univariate

    by eric.ward, last updated 5/26/08, sharing set to public
    This script writes and runs the data cloning procedure described by Lele et al. (2007, Ecology Letters). The routine is in R, and requires the user to install OpenBUGS before running. The number of clones can (and should) be modified. For this simple example, 100 clones takes ~ 2 minutes on my 2.5 year old laptop (1.66Ghz, 1GB RAM). More details and diagnostics can be found in the multivariate cloning project.
  • Estimating heritability from time series

    by mdscheuerell, last updated 1/5/11, sharing set to public

    We use a multivariate state-space model and a time series of yearly migration dates for sockeye salmon to estimate the heritability coef from the classic breeder's equation.

    The 2 files below are the dataset and the R script.

  • MARSS Dev Site

    MARSS is an R package to fit mulitvariate autoregressive state-space (MARSS) models with Gaussian errors to multivariate time series data.  Developers: Eli Holmes, Eric Ward, Mark Scheuerell and Kellie Wills. This is the DEVELOPMENT site for the MARSS.  For the current MARSS  release go to CRAN or download straight from the R GUI using "Install Packages" menu. To see what's coming in the next version, click NEWS in the files.

    To install patches
    source("patchfile.r") #replace with actual file name
    library(R.utils) #install if needed
    #replace patch_fun with function name in patchfile.r
    reassignInPackage("patch_fun", pkgName="MARSS", patch_fun)
    To install the development version
    library(devtools)
    install_url("https://fishbox.nwfsc.noaa.gov/zip/e2holmes/MARSS%20Dev%20Site/MARSS_source.zip")
