Characterizing superspreading potential of infectious disease: Decomposition of individual transmissibility
Fig 6
The power and type I error rate of the likelihood ratio (LR) test for Delaporte distribution against negative binomial (NB) distribution.
Panels (A) and (D) show the test statistics (dots) from LR test, and the critical threshold (red horizontal dashed line) for p-value < 0.05. In panel (A), the ‘+’ dots are 10000 pseudo datasets generated by random sampling with replacement from the real-world datasets, and the circle dots represent datasets #1-#5. Panels (B) and (E) summarized the power and type I error rate of LR test for Delaporte distribution against NB distribution as a function of sample size. Panels (C) and (F) summarized the power and type I error rate of LR test with sample size reciprocal-distributed from 30 to 3000. In panel (D), the ‘×’ dots are generated by 10000 datasets generated by Monte Carlo sampling from NB distributions. In panels (B) and (C), the horizontal dashed line is the threshold of power at 0.80. In panels (E) and (F), the horizontal dashed line is the threshold of type I error rate at 0.05.
