Created: 2014-08-29 11:04:10 | Last updated: 2014-09-30 09:35:02

The pack contains three workflows, 13 files and 2 documentations (tutorials to run the workflows).Workflows:1) Demography of the killer whales.2) Resident killer whale-chinook salmon interactions.3) Exploration of fishing scenarios.These workflow uses input data of two different populations of Orcas in the northeastern Pacific Ocean of Canada and the U.S. But these workflows can also use input data from other populations of the Orcas in the world (see requirements for data entry in the docume...

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...
