Workflow Parametric Bootstrap or Resample a project... (3)

Thumb
The Parametric Bootstrap or Resample a projection matrix Workflow provides an environment to resample a projection matrix using a multinomial distribution for transitions and a log normal distribution for fertilities (Stubben, Milligan, and Nantel. 2011). The resample is based on number of plants surveyed. The projection matrix A is first split into separate transition and fertility matrices. Dead fates are added to the transition matrix and the columns are then sampled from a Multinomial dis...

Workflow Transient Dynamics. (3)

Thumb
This workflow produces plots of the short-term dynamics and convergence to stable stage distribution using stage vector projections. ============================================================ 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 was created based on Package ‘popbio’ in R. Stubben, C & B. Milligan. 2007. Estimating and Anal...

Workflow Eigen analysis (3)

Thumb
The Eigen analysis results are a set of demographic statistics: 1) Lambda or dominant eigenvalue: The population will be stable, grow or decrease at a rate given by lambda: eg: ? = 1 (population is stable), ? > 1 (population is growing) and finally ? < 1 (populatiopn is decreasing) . 2) The stable stage distribution: It is the proportion of the number of individuals per stage and it is given by (w). Elasticity and Sensitivity: Sensitivity and elasticity analyses are prospective analyses....
