论文摘要
我们提出了一个新的模型，用于分析结构零的组成数据。受\ cite {butler2008}的启发，他在数据中提出了一个模型，我们提出了一个模型，该模型以不同的方式处理零值。我们没有将每个零值投影到顶点，而是将它们投影到相应的边缘上，并适合零审核的多元模型。
We present a new model for analyzing compositional data with structural zeros. Inspired by \cite{butler2008} who suggested a model in the presence of zero values in the data we propose a model that treats the zero values in a different manner. Instead of projecting every zero value towards a vertex, we project them onto their corresponding edge and fit a zero-censored multivariate model.
