| Abstract: | In this article, the zero-one inflated binomial mixed regression is proposed to model proportional data with large frequencies of both zeros and binomial denominators. Score tests for assessing both extra zeros and extra binomial denominators in proportional data are developed. The empirical levels and empirical powers of the score test statistics are evaluated using a simulation study. Finally, the application of the proposed model is illustrated on the whitefly data. |
