摘要：

Watson and Nguyen (1985) and Watson (1987) consider the problem of plotting confidence regions in a ternary diagram, for a trinomial probability vector pi, based on Pearson's chi-2. Their results are extended to the power-divergence family of statistics resulting in confidence regions of diverse shapes and sizes. The members of family with the most accurate coverage probabilities are lambda = 2/3 and lambda = 1/2.
