摘要

本文提出了R包plot3logit，它使三叉回归模型的协变量效应可以用三叉图来表示。该图的目的是根据回归量值的变化对因变量概率分布的影响来帮助解释回归系数。这样的更改可能涉及单个回归量，也可能涉及一组回归量(复合更改)，并且该包允许以用户友好的方式处理这两种情况。此外，plot3logit可以计算和绘制协变量变化影响的置信区域，使多个变化和剖面能够共同表示和比较。上游和下游的兼容性使得该包能够与R以外的其他R包或应用程序一起工作。

plot3logit: Ternary Plots for Interpreting Trinomial Regression Models

This paper presents the R package plot3logit which enables the covariate effects of trinomial regression models to be represented graphically by means of a ternary plot. The aim of the plot is helping the interpretation of regression coefficients in terms of the effects that a change in values of regressors has on the probability distribution of the dependent variable. Such changes may involve either a single regressor, or a group of them (composite changes), and the package permits both cases to be handled in a user-friendly way. Moreover, plot3logit can compute and draw confidence regions of the effects of covariate changes and enables multiple changes and profiles to be represented and compared jointly. Upstream and downstream compatibility makes the package able to work with other R packages or applications other than R .
