  1. Reporting probabilities of (i) survey reporting, P, (ii) reporting probabilities conditional on mote detection, P s , and (iii) proportion of differences in mote and survey data due to underreporting, N 1 ' sm - N 1 sm / N 3 sm . Percentages for P, P s , and N 1 ' sm - N 1 sm / N 3 sm were calculated for four predefined different contact duration categories and for five different networks (all participating individuals included; only participating individuals with a degree of more than 1, 2, 3, or 4 included), all compared to P values calculated from a previous study [38].
