    Snippet: Model comparison 467 We compare the goodness of fit of models with di erent asymptomatic and pre-symptomatic relative infectiousness (between 0% and 2% of that of VL cases), with and without additional within-household transmission, to test di erent assumptions about how infectious asymptomatic and pre-symptomatic individuals are, using DIC (41). DIC measures the trade-o between model fit and complexity and lower values indicate better fit. Since.....
    Document: Model comparison 467 We compare the goodness of fit of models with di erent asymptomatic and pre-symptomatic relative infectiousness (between 0% and 2% of that of VL cases), with and without additional within-household transmission, to test di erent assumptions about how infectious asymptomatic and pre-symptomatic individuals are, using DIC (41). DIC measures the trade-o between model fit and complexity and lower values indicate better fit. Since some variables were not observed, we use a version of DIC appropriate for missing data from (42), which is based on the complete data likelihood L(â—Š; Z) = P(Y, X|â—Š). This is equivalent to the standard version of DIC for fully observed data except that it is averaged over the missing data:
