Fig. 2From: Sample size and power calculations for detecting changes in malaria transmission using antibody seroconversion rateDistributions of the change point estimates according to the 12 parameter combinations used in the simulation study. For each parameter combination, the plot represents the variations in the distribution of change point estimates obtaining from 1000 simulated data sets with a given sample size using a profile likelihood method for the respective estimation. The corresponding 95 % confidence intervals for the true change point are shown on top of each plotBack to article page
