Generalized ordinal patterns allowing for ties and their applications in hydrology
Computational Statistics & Data Analysis, 2022 When using ordinal patterns, which describe the ordinal structure within a data vector, the problem of ties appeared permanently. So far, model classes were used which do not allow for ties; randomization has been another attempt to overcome this problem. Often, time periods with constant values even have been counted as times of monotone increase.

Ordered samples control charts for ordinal variables [PDF]
, 2005 The paper presents a new method for statistical process control when ordinal variables are involved. This is the case of a quality characteristic evaluated by an ordinal scale.

Binary and Ordinal Random Effects Models Including Variable Selection [PDF]
, 2010 A likelihood-based boosting approach for fitting binary and ordinal mixed models is presented. In contrast to common procedures it can be used in high-dimensional settings where a large number of potentially influential explanatory variables is available.

Permutation Entropy: New Ideas and Challenges
Entropy, 2017 Over recent years, some new variants of Permutation entropy have been introduced and applied to EEG analysis, including a conditional variant and variants using some additional metric information or being based on entropies that are different from the ...

Diagnosis of Mild Cognitive Impairment With Ordinal Pattern Kernel
IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022 Mild cognitive impairment (MCI) belongs to the prodromal stage of Alzheimer's disease (AD). Accurate diagnosis of MCI is very important for possibly deferring AD progression. Graph kernels, which measure the similarity between paired brain connectivity networks, have been widely used to diagnose brain diseases (e.g., MCI) and yielded promising ...

Ordered Choice Models: Ordinal Logit and Ordinal Probit [PDF]
, 2022 Classical ordinal logit and probit models are used in studies where the dependent variable is categorical and ordinal. In order to use these models, the assumption of parallel slopes must be met.

Assignment of ordinals to patterns of resemblance
Journal of Symbolic Logic, 2007 AbstractIn [2] T. J. Carlson introduces an approach to ordinal notation systems which is based on the notion of Σ1-elementary substructure. We gave a detailed ordinal arithmetical analysis (see [7]) of the ordinal structure based on Σ1-elementarily as defined in [2].

Ordinal patterns in epileptic brains: Analysis of intracranial EEG and simultaneous EEG-fMRI [PDF]
, 2013 Epileptic seizures are associated with high behavioral stereotypy of the patients. In the EEG of epilepsy patients characteristic signal patterns can be found during and between seizures.

Ordinal Pattern Based Entropies and the Kolmogorov–Sinai Entropy: An Update
Entropy, 2020 Different authors have shown strong relationships between ordinal pattern based entropies and the Kolmogorov−Sinai entropy, including equality of the latter one and the permutation entropy, the whole picture is however far from being complete. This

Predicting Change in Emotion through Ordinal Patterns and Simple Symbolic Expressions
Mathematics, 2022 Human interlocutors may use emotions as an important signaling device for coordinating an interaction. In this context, predicting a significant change in a speaker’s emotion may be important for regulating the interaction.
