burnIn |
non-negative integer indicating the number of burn in samples before recording the first sample |
samples |
positive integer indicating the number of samples to record |
thin |
positive integer indicating how to thin the samples |
print |
positive integer indicating how often to print an update to the R console |
fileNames |
list of files locations to write samples. Should be vector of strings with length 5 (7 if using the extended mixed membership model) corresponding to: Theta, Alpha_0, Ksi, Lambda, Z, (P, rho). |
newFiles |
0 if samples should be appended to existing files; 1 if samples should overwrite any existing files |
omega |
tuning parameter for MH step for alpha. |
eta |
tuning parameter for MH step for ksi |
whichWrite |
which parameters to write to disk. Writing the individual parameters can significantly increase computational time when the number of individuals is large |
extended |
boolean whether to estimate the extended model or not |
mmMCMCFit
draws samples from the posterior distribution of a mixed membership model
given a set of observed data. The sampler takes Metropolis Hastings steps to sample the α_0
and ξ parameters and samples the remaining θ, λ_i and Z parameters
with a Gibbs sampler.
