Graphical Models for Ordinal Data. [PDF]
J Comput Graph Stat, 2015 A graphical model for ordinal variables is considered, where it is assumed that the data are generated by discretizing the marginal distributions of a latent multivariate Gaussian distribution. The relationships between these ordinal variables are then described by the underlying Gaussian graphical model and can be inferred by estimating the ...

Classification of Ordinal Data [PDF]
, 2006 Classification of ordinal data is one of the most important tasks of relation learning. In this thesis a novel framework for ordered classes is proposed. The technique reduces the problem of classifying ordered classes to the standard two-class problem. The introduced method is then mapped into support vector machines and neural networks. Compared with

PENGOLAHAN DATA BERSKALA ORDINAL
Sigma-Mu, 1970 Dalam analisis Multivariat, pengolahan data terkadang mengharuskan data berskala interval / metrik. Apabila data yang dihadapi berskala ordinal, sebaiknya digunakan analisis multivariat nonparametrik. Namun, analisis ini mempunyai banyak kesulitan. Karena software yang mampu mengakomodasi teknik-teknik seperti ini masih kurang.
