bootstrapping lambda values from projections matrices
I'm working with a population projections matrix model from demographic
data. The dominant eigenvalue of the matrix is the growth rate of the
population (lambda). I would like to estimate confidence intervals for the
lambda values with bootstrap.
The function for calculating the eigenvalue I wrote like this:
Now, in the pooled matrix from all years I would like to sample in a way
that the number of bootstrap samples taken from each year is equal to the
number of data points from each year. Therefore I'm defining strata=year.
