simEcm {capwire} | R Documentation |
Simulates capture count data under the assumptions of the Equal Capture Model (ECM), where all individuals are assumed to have an equal probability of being captured
simEcm(n, s)
n |
Number of individuals in the population |
s |
Total number of samples collected |
A two-column data frame with the first column specifiying the capture class (i.e. individuals caught i times) and the second column specifying the number of individuals in each class.
The data frame can be used as the data argument for any of the model-fitting functions implemented in capwire
