varEst

Finds the best estimates of mean and environmental variance for beta-binomial
vital rates using the approximation method of Akcakaya (2002)

Construct and analyze projection matrix models from a demography study of marked individuals classified by age or stage. The package covers methods described in Matrix Population Models by Caswell (2001) and Quantitative Conservation Biology by Morris and Doak (2002).
