abund.ch.prob {CTFS} | R Documentation |
The probability that N0 = N1 is computed.
abund.ch.prob(N0, N1, recrate, survrate)
N0 |
abundance in first census |
N1 |
abundance in second census |
recrate |
number of recruits / N1 |
survrate |
number of survivors / N0 |
See CTFS.abundance
for details on the computation of
abundance and associated functions.
This function is designed to be called from
abundance.change.calculation
. It can be used independently
if the number of recruits and survivors are known. The probability
returned is the sum of a biniomial (survivorship) and poisson
(recruitment) distribution. The arguments can be vectors of any length.
This function does not work with multi-dimensional arrays. To use if for
these, use abundance.change.calculation
prob |
vector of probabilities of same length as the arguments |
