This is documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with the same name.The Keyfitz’s delta Workflow provides an environment to calculate the Keyfitz delta value. Keyfitz’s delta is a measure of the distance between any two probability vectors (Keyfitz 1968). In this case is a measure of the distance between n (Observed Stage Distribution) and w (Stable Stage Distribution). The maximum value is 1 and the minimum value is 0 (w...

Workflow Cohen’s cumulative distance (1)

Thumb
The Cohen’s cumulative distance Workflow provides an environment to calculate the Cohen’s cumulative distance. The Cohen’s cumulative distance measures the difference between observed and expected vectors along the matrix path that the population would take to reach the expected population vector. It is a function of both the observed stage distribution (n0) and the structure of the matrix (A) (Williams et al 2011). Cohen’s cumulative distance will not work for reducible matrices or imprimiti...

This pack contains a workflow, a file and documentation (tutorial to run the workflow). 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 ar...

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Bootstrap of observed census transitions (confidence intervals of λ) workflow for local execution calculates bootstrap distributions of population growth rates (λ), stage vectors, and projection matrix elements by randomly sampling with replacement from a stage-fate data frame of observed transitions. The goal of a demographic analysis is very often to estimate lambda, because lambda is es...

Pack Net reproductive rate (Ro) pack


Created: 2014-07-04 13:59:07 | Last updated: 2014-07-25 11:25:32

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The . Net reproductive rate (Ro) Workflow provides an environment to calculate the net reproductive rate (Ro). Ro is the mean number of offspring by which a new-born individual will be replaced by the end of its life, and thus the rate by which the population increases from one generation to the next.
