abc_batch {gk}

Single batch of ABC

Description

Interal function carrying out part of ABC inference calculations

Usage

abc_batch(sobs, priorSims, simStats, M, v = NULL)

Arguments

sobs

Vector of observed summary statistics.

priorSims

Matrix whose rows are vector of parameters drawn from the prior.

simStats

Function mapping a vector of parameters to summary statistics.

M

How many simulations to accept in this batch.

v

Optional vector of estimated variances for each summary statistic

Details

Outputs a list containing: 1) matrix whose rows are accepted parameter vectors, and a column of resulting distances 2) value of v. If v is not supplied then variances are estimated here and returned. (The idea is that this is done for the first batch, and these values are reused from then on.)
