Table 1.

Difference in deviance information criteria (DIC) relative to the best-fitting model, used to confirm absence of common parameters for secondary transmission rates, associated with the donor, the recipient, or both

Model		DIC	p̂
Full		0	21.0
Donors same	β[FF] = β[UF]; β[FU] = β[UU]	25	15.7
Recipients same	β[FF] = β[FU]; β[UF] = β[UU]	482	11.5
Cross same	β[FU] = β[UF]	50	17.3
All rates same	β[FF] = β[FU] = β[UF] = β[UU]	921	7.4

The estimated effective number of parameters is denoted p̂. For brevity, the time dependence of β is omitted.
