We show that the family of asymmetric distributions studied in a recent publication in the International Statistical Review is equivalent to the family of two‐piece distributions. Moreover, we show that the location‐scale asymmetric family proposed in that publication is non‐identifiable (overparameterised), and it coincides with the family of two‐piece distributions after removing the redundant parameters.

致编辑的信：“关于基于分位数的非对称分布族：属性和推论”

我们表明，最近在《国际统计评论》上发表的文章研究的非对称分布族等同于两部分分布族。此外，我们表明该出版物中提出的位置尺度不对称族是不可识别的（过参数化），并且在去除冗余参数后与两件式分布族相符。
