package prbnmcn-dagger

p is the type of particles

o is the type of particle outputs.

r is the type of the scores associated to each particle

iter allows to iterate on the current population of particles.

fold allows to fold on the current population of particles.

get_output p is the output of the particle at the last yield point. Returns None if the particle has terminated. See the documentation for yield in Smc_inference.

get_score p is the unnormalized score of the particle.

append p r appends particle p with score r to the next population.

total () is the total mass of the current population.

size () is the cardinality of the current population.

ess () is the estimated sample size. Varies between 0 and the cardinality of the current population. Computed as \left(\sum_{i=1}^N w_i^2\right)^{-1}, where N is equal to size () and the w_i are the normalized scores of each particle.
