Workflow Bootstrap of observed census transitions. (3)

Thumb
This workflow calculates bootstrap distributions of population growth rates (?), 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 estimated from imperfect data, such estimation are uncertain. Therefore, when the results have policy implications it is important to quantify that uncertainty. Confidence interval is one of ...

Thumb
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. ...
