To speed up compuation, animals with the same capture history and design matrix are accumulated and represented by a frequency. Computes starting values for Phi and p parameters from the list of design matrices and the summarized data list including ch matrix and first and last vectors. If any values are missing (NA) or abs(par)>5, they are set to 0.
js.accumulate(x, model_data, nocc, freq, chunk_size)modified model_data list that is accumulated
data
list of design matrices, fixed parameters and time intervals all which can vary by animal
number of capture occasions
frequency of each capture history before accumulation
size that determines number of pieces of data/design matrix that are handled. Smaller chunk_size requires more time but less memory. 1e7 is default set in cjs.
