DirichletReg: Dirichlet Regression for Compositional Data in R Dirichlet regression models can be used to analyze a set of variables lying in a bounded interval that sum up to a constant (e.g., proportions, rates, compositions, etc.) exhibiting skewness and heteroscedasticity, without having to ...

Dirichlet regression aims to predict compositional data and can be used in many fields such as ecology, health, and economy. Available in Excel using the XLSTAT software.
I am trying to use the predicted probabilities from a multinomial regression using multinom function from the nnet package in R to estimate the parameters for a Dirichlet distribution while taking into account the standard errors. Below is an example of what I'm trying to do. I have two sets...
首先我们先了解下Dirichlet-multinomial regression。 让我们从数学层面开始: 假设从正常组织取了sample i,正常组织本身包含了p种cell type,假设各种cell type出现的概率为 Cell probability , sample i中各种cell type出现的数目为 Number of cell type sample i中共有N个cell,全部细胞的总和就是, ...
