Maximum likelihood estimate of the probability of transmission of T. cruzi.
(A) profile likelihood, maximum likelihood estimate (MLE) of the probability of transmission T, and its 95% maximum likelihood confidence interval (MLCI). (B) Distribution of the MLE of T obtained from the sensitivity analyses (1000 replications). Grey and black horizontal bars on the top of the figure represent the 95% MLCI (with the grey dot corresponding to the MLE) and the interval including 95% of the MLE estimates obtained from the sensitivity analysis.
Figure 2.
Sensitivity analyses of the probability of transmission of T. cruzi.
Each panel gives the distribution of point estimates of T obtained from the sensitivity analyses (1000 replications). Panels A, B and C correspond to datasets 2, 3 and 4, respectively, while panels D, E and F correspond to each of the three villages included in dataset 5. Black bars represent the interval including 95% of the point estimates obtained from the sensitivity analysis. The grey dots and bars represent the maximum likelihood estimate (MLE) and 95% maximum likelihood confidence interval (MLCI) obtained from the dataset 1 for comparison (see Figure 1).
