Table 1

Some of the types of mixing matrices used in the paper. Three of the mixing matrices discussed in Methods: a) fully assortative mixing (RDIAG), b) "Realistic" assortative mixing (DIAG) and c) the default mixing matrix (DEF) of Edmunds et al (2000). Succeeding rows and columns represent the age groups 0–1 year, 2–4 years, 5–10 years, 11–17 years and 18+ (e.g. for DIAG β3 is the element corresponding to contacts between those in the 5–10 year age group and their peers in the same age group)

a) DIAG
b) RDIAG
c) DEF
