Get abundance probabilities — get_abund

Get probabilities of abundances, as the multinomial probabilities, for each species at each time step as predicted by a TS model.

get_abund_probabilities(
  subsetted_dataset_item,
  fitted_lda,
  fitted_ts,
  max_sims = NULL
)

Arguments

subsetted_dataset_item	list with (at least) element `$full`: unaltered dataset.
fitted_lda	LDA fit to either a subsetted or a full dataset
fitted_ts	TS fit to that LDA
max_sims	defaults NULL. If supplied, will randomly draw `max_sims` draws from the posterior and return probabilities just for those. Useful for speeding things up.

Value

list of matrices of abundance probabilities for each species (columns) for each timestep (rows), with one list for each draw from the posterior (or max_sims, if supplied).

Details

Gets one matrix of probabiltiies for each draw from the posterior for estimates of changepoint locations and model parameters (in this case just the intercept).
