extract_prop {bayesmove} | R Documentation |
Calculates the mean of the posterior for the proportions of each behavior within track segments. These results can be explored to determine the optimal number of latent behavioral states.
extract_prop(res, ngibbs, nburn, nmaxclust)
res |
A list of results returned by |
ngibbs |
numeric. The total number of iterations of the MCMC chain. |
nburn |
numeric. The length of the burn-in phase. |
nmaxclust |
numeric. A single number indicating the maximum number of clusters to test. |
A matrix that stores the proportions of each state/cluster (columns) per track segment (rows).
