Table 1.

Mean number of data-generation steps per final particle for each population, based on 1,000 particles, under algorithms ABC-PRC and ABC-REJ

t	ϵt	ABC-PRC	ABC-REJ
			Prior	Posterior
1	2.000	4.907	–	–
2	0.500	4.899	–	–
3	0.025	66.089	400.806	21.338
	Total	75.895	400.806	21.338

Final two columns use U(−10, 10) prior and known posterior mixture of normals as sampling distributions.
