Matrix Population Model construction and analysis v20


HelpDocumentation Myexp_iconView on myExperiment

The Matrix Population Models Workflow provides an environment to create stage-matrices with no density dependence and to perform several analyses on them:
- Eigen analysis;
- Age specific survival;
- Generation time (T);
- Net reproductive rate (Ro);
- Transient Dynamics;
- Bootstrap of observed census transitions (Confidence intervals of lambda);
- Survival curve;
- Keyfitz delta;
- Cohen's cumulative distance.

If multiple year transitions are selected, the results will be ordered by year.

This workflow requires an instance of Rserve on localhost

This workflow has been created by the Biodiversity Virtual e-Laboratory (BioVeL http://www.biovel.eu/) project. BioVeL is funded by the EU’s Seventh Framework Program, grant no. 283359.

This workflow uses R packages ‘popbio’ (Stubben & Milligan 2007; Stubben, Milligan & Nantel 2011) and 'popdemo' (Stott, Hodgson and Townley 2013).
