Table 1.

Probabilities of methylation events at site j, h_λ(q_ij, d_ij; p_ij) = Pr ((Q_ij, D_ij) = (q_ij, d_ij)|P_ij = p_ij). The dagger † indicates cases not possible under the assumption of no active removal of methyl groups on the parent strand.

(Qij, Dij) = (qij, dij)	Pij = pij	hλ (qij, dij; pij)	Methylation Event
(0, 0)	1	0	†Assumed not to occur
(0, 1)	1	0	†Assumed not to occur
(1, 0)	1	1 − μj	Failure of maintenance
(1, 1)	1	μj	Maintenance
(0, 0)	0	(1 − δp;j)(1 − δd;j)	No de novo on parent or daughter
(0, 1)	0	(1 − δp;j) δd;j	De novo on daughter but not parent
(1, 0)	0	δp;j(1 − δd;j)	De novo on parent but not daughter
(1, 1)	0	δp;jδd;j	De novo on parent and daughter
