A non-parametric method to estimate the number of clusters

TL;DR: The proposed slope statistic is a non-parametric and data driven approach for estimating the number of clusters in a dataset that uses the output of any clustering algorithm and identifies the maximum number of groups that breaks down the structure of the dataset.
Journal ArticleDOI

A heteroscedastic structural errors-in-variables model with equation error

TL;DR: In this article, the authors deal with the limiting distribution of the maximum likelihood and method-of-moments estimators for the line parameters of the regression model and use the delta method to achieve it, making it possible to build joint confidence regions and hypothesis testing.
Journal ArticleDOI

Functional clustering of time series gene expression data by Granger causality

TL;DR: This kind of analysis can be used as a complementary approach for functional clustering, wherein genes would be clustered not solely based on their expression similarity but on their topological proximity built according to the intensity of Granger causality among them.
Journal ArticleDOI

A classical measure of evidence for general null hypotheses

TL;DR: This paper proposes an objective measure of evidence for very general null hypotheses that satisfies logical requirements and concludes that it can be used to establish objective states of belief on the subsets of Θ .
Journal ArticleDOI

Influence diagnostics in Birnbaum–Saunders nonlinear regression models

TL;DR: In this article, the influence of observations in the class of Birnbaum-Saunders nonlinear regression models, which is useful in lifetime data analysis, is considered. But the authors do not consider the effect of individual and generalized leverage.
