Testing Normal Means: The Reconcilability of the P Value and the Bayesian Evidence

open access: yesThe Scientific World Journal, 2013
The problem of reconciling the frequentist and Bayesian evidence in testing statistical hypotheses has been extensively studied in the literature. Most of the existing work considers cases without the nuisance parameters which is not the frequently ...

On the Elimination of Nuisance Parameters [PDF]

open access: yesJournal of the American Statistical Association, 1977
Abstract Eliminating nuisance parameters from a model is universally recognized as a major problem of statistics. A surprisingly large number of elimination methods have been proposed by various writers on the topic. In this article we propose to critically review two such elimination methods.

Higher-Order Expansions for Estimators in the Presence of Nuisance Parameters

open access: yesMathematics
Higher-order asymptotic methods for nonlinear models with nuisance parameters are developed. We allow for both one-step estimators, in which the nuisance and parameters of interest are jointly estimated; and also two-step (or iterated) estimators, in ...

Blinded sample size re-estimation in a comparative diagnostic accuracy study

open access: yesBMC Medical Research Methodology, 2022
Background The sample size calculation in a confirmatory diagnostic accuracy study is performed for co-primary endpoints because sensitivity and specificity are considered simultaneously.

Forecasting Using Time Varying Meta-Elliptical Distributions with a Study of Commodity Futures Prices [PDF]

open access: yes, 2006
We propose a methodological approach to the forecast and evaluation of multivariate distributions with time varying parameters. For reasons related to feasible inference attention is restricted to meta-elliptical distributions.

Nonlinear dynamics in economics and finance and unit root testing [PDF]

open access: yes, 2013
This paper illustrates the flexibility of the ESTAR model to encompass a number of different characteristics found in economic and financial series, such as multiple equilibria, complex dynamics, chaotic-like behavior, and spurious trends.

Semiparametric models with single-index nuisance parameters [PDF]

open access: yes, 2013
In many semiparametric models, the parameter of interest is identified through conditional expectations, where the conditioning variable involves a single-index that is estimated in the first step.

Permutation Tests for Regression, ANOVA, and Comparison of Signals: The permuco Package

open access: yesJournal of Statistical Software, 2021
Recent methodological researches produced permutation methods to test parameters in presence of nuisance variables in linear models or repeated measures ANOVA. Permutation tests are also particularly useful to overcome the multiple comparisons problem as

The polynomial and the Poisson measurement error models: some further results on quasi score and corrected score estimation [PDF]

open access: yes, 2005
The asymptotic covariance matrices of the corrected score, the quasi score, and the simple score estimators of a polynomial measurement error model have been derived in the literature.

Estimating parameters in the presence of many nuisance parameters [PDF]

open access: yes, 2013
This paper considers estimation of parameters for high-dimensional time series with the presence of many nuisance parameters. In particular we are interested in data consisting of p time series of length n, with p to be as large or even larger than n ...
