Composite Likelihood Methods Based on Minimum Density Power Divergence Estimator

Entropy, 2017
In this paper, a robust version of the Wald test statistic for composite likelihood is considered by using the composite minimum density power divergence estimator instead of the composite maximum likelihood estimator.

Score Statistics for Current Status Data: Comparisons with Likelihood Ratio and Wald Statistics [PDF]

The International Journal of Biostatistics, 2005
In this paper we introduce three natural ``score statistics" for testing the hypothesis that F(t_0)takes on a fixed value in the context of nonparametric inference with current status data. These three new test statistics have natural interpretations in terms of certain (weighted) L_2 distances, and are also connected to natural ``one-sided" scores. We

Confidence intervals for rainfall dispersions using the ratio of two coefficients of variation of lognormal distributions with excess zeros.

PLoS ONE, 2022
Rainfall fluctuation is directly affected by the Earth's climate change. It can be described using the coefficient of variation (CV). Similarly, the ratio of CVs can be used to compare the rainfall variation between two regions. The ratio of CVs has been

Wald's Equation for a Class of Denormalized $U$-Statistics

The Annals of Probability, 1993
For the sequence \(\{X_ n\}\) of zero mean, i.i.d. random variables define \(S_{k,n}=\sum'X_{i_ 1}\ldots X_{i_ k}\), where \(\sum'\) denotes the sum over \(1 \leq i_ ...

Two models for linear comparative calibration [PDF]

International Journal of Metrology and Quality Engineering, 2012
We consider the comparative calibration problem in the case when linear relationship is assumed between two considered measuring devices with possibly different units and precisions.

Validating attribute hierarchies in cognitive diagnosis models

Frontiers in Psychology
Cognitive diagnosis models (CDMs) are restricted latent class models that are widely used in educational and psychological fields. Attribute hierarchy, as an important structural feature of the CDM, can provide critical information for inferring ...

Robust-BD Estimation and Inference for General Partially Linear Models

Entropy, 2017
The classical quadratic loss for the partially linear model (PLM) and the likelihood function for the generalized PLM are not resistant to outliers. This inspires us to propose a class of “robust-Bregman divergence (BD)” estimators of both the parametric
