Exit.ci.iid: Compute confidence interval for probability of extinction...
In ashander/matrixmodels: Tools for analysis of matrix population (models)

Compute confidence interval for probability of extinction within specified timeframe

1 2	Exit.ci.iid(time, ci.width, reps, n.0, matrices, p, t.max, nreps, qe = 0, weight.sum = NULL)

`time`	time at which to calculate CI
`ci.width`	width (in probability units) of confidence interval to produce
`reps`	number of distinct cdfs to compute, don't make this too large
`n.0`	initial number in stages
`matrices`	is a d^2 x s matrix, where d number of stages, s the number of matrixes
`p`	vector of probabilities for drawing each matrix
`t.max`	time to stop and compute population size
`nreps`	number of replicates to compute the exit time distribution over within each run
`qe`	quasi-extinction threshold
`weight.sum`	weighting vector for summation

This MAY NOT fully represent the variablity in the system this function does not use distribution of vital rates, but rather repeated draws of complete matrices. See Fieberg and Ellner (2003, Ecology) and Morris and Doak (2003).
