ctStanParnames
Gets internal stan parameter names of a ctStanFit object sampled via stan based on specified substrings.

vector of character strings, parameter names of the stan model containing any of these strings will be returned. Useful strings may be 'pop_' for population means, 'popsd' for population standard deviations, or specific combinations such as 'pop_DRIFT' for the population means of temporal dynamics parameters |
