متن کاملPlackett-Luce regression: A new Bayesian model for polychotomous data
Multinomial logistic regression is one of the most popular models for modelling the effect of explanatory variables on a subject choice between a set of specified options. This model has found numerous applications in machine learning, psychology or economy. Bayesian inference in this model is non trivial and requires, either to resort to a MetropolisHastings algorithm, or rejection sampling wi...
متن کاملHeritability of polychotomous characters.
Characters with phenotypic expression consisting of a response in one of several mutually exclusive and exhaustive categories are considered. Formulae relating heritability in the discrete, outward scale to heritability in underlying normal and exponential scales are presented. For the normal case with two response categories, results reduce to the well-known formula for heritability of binary ...
متن کاملExperiments in Polychotomous Classification
A central problem in pattern recognition is the classi cation of a feature vector into one of several possible classes. In polychotomous classi cation the number of possible classes is higher than two. Given a set of training vectors with known classes, a classi er can be constructed using for example some density estimation or regression method. In a typical approach one estimates, using all t...
متن کاملThe Analysis of Bayesian Probit Regression of Binary and Polychotomous Response Data
The goal of this study is to introduce a statistical method regarding the analysis of specific latent data for regression analysis of the discrete data and to build a relation between a probit regression model (related to the discrete response) and normal linear regression model (related to the latent data of continuous response). This method provides precise inferences on binary and multinomia...
