pymc.backends.base.BaseTrace.get_sampler_stats# BaseTrace.get_sampler_stats(stat_name, sampler_idx=None, burn=0, thin=1)[source]# Get sampler statistics from the trace. Parameters stat_name: str sampler_idx: int or None burn: int thin: int Returns If the sampler_idx is specified, return the statistic with the given name in a numpy array. If it is not specified and there is more than one sampler that provides this statistic, return a numpy array of shape (m, n), where m is the number of such samplers, and n is the number of samples.
