Improving GDP Measurement:A Measurement-Error Perspective
Income Output expenditure business cycle expansion contraction recession turning point state-space model dynamic factor model forecast combination
2015/9/18
We provide a new measure of historical U.S. GDP growth, obtained by applying optimal signal-extraction techniques to the noisy expenditure-side and income-side GDPestimates. The quarter-by-quarter val...
Sequential Design of Reliability Studies to Evaluate Measurement Error of Biomarkers
Sequential Design Reliability Studies Measurement Error Biomarkers
2015/3/20
Studies have suggested that oxidative stress might be implicated in the risk of human infertility. For this reason, the BioCycle study, a longitudinal study to assess the effects of endogenous hormone...
Statistical Methods for Nonlinear Dynamic Models with Measurement Error Using the Ricker Model

2014/12/8
In ecological population management, years of animal counts are fit to nonlinear, dynamic models (e.g. the Ricker model) because the values of the parameters are of interest. The yearly counts are sub...
Data Combination from Multiple Sources Under Measurement Error
Intercomparison Measurement Error Reference Material
2014/12/8
Regulatory Agencies are responsible for monitoring the performance of particular measurement communities. In order to achieve their objectives, they sponsor Intercomparison exercises between the membe...

Estimation of Variance and Its Properties in Measurement Error Model
Measurement error model independence unbiased estimator non-negative estimator.
2011/11/11
This paper introduces variance estimators of Y in measurement error model X=Y+E with known Var(E). An unbiased estimator and an adjust non-negative estimator of Var(Y) are given. Meanwhile, some prope...
Child Mental Health and Educational Attainment: Multiple Observers and the Measurement Error Problem
child mental health education Strengths and Difficulties Questionnaire measurement error
2012/10/25
We examine the effect of survey measurement error on the empirical relationship between child mental health and personal and family characteristics, and between child mental health and educational pro...
Estimation in autoregressive model with measurement error
autoregressive model markov chain weak dependent deconvolution semi-parametric nonlinear autoregressive model
2011/6/16
Consider an autoregressive model with measurement error: we observe
Zi = Xi+εi, where Xi is a stationary solution of the equation Xi = f0(Xi−1)+ξi. The
regression function f0 is known up to ...
Bias terms of measurement error in treatment by expected estimating equations
Estimating equations Bias Measurement error
2010/11/1
Inference for the effect of treatment on an outcome often suffers from the unavailability of valid measurements of treatment. Due to this, systematic errors in measurements of treatment occur frequent...
Measurement error and convolution in generalized functions spaces
Measurement error convolution generalized functions spaces
2010/12/9
This paper considers convolution equations that arise from problems such as deconvolution and non-parametric regression with errors in variables. The equations are examined in spaces of generalized fu...
Does adjustment for measurement error induce positive bias if there is no true association?
adjustment measurement error positive bias true association
2010/3/18
This article is a response to an off-the-record discussion that I had at an international meeting of epidemiologists. It centered on a concern, perhaps widely spread, that measurement error
adjustmen...
Variable selection in measurement error models
errors in variables estimating equations measurement error models non-concavepenalty function SCAD semi-parametric methods
2010/3/10
Measurement error data or errors-in-variable data have been collected in many studies. Natural
criterion functions are often unavailable for general functional measurement error models due
to the la...
How measurement error in dichotomous predictors affects the analysis of continuous criteria
Measurement error in predictors predictor reliability regression analysis
2009/12/30
If the mean of a criterion variable differs across groups, measurement error in the grouping variable leads to bias in the estimated size of the effect. Similar to the classical errors-in-variables mo...
A Reanalysis of Toomela (2003): Spurious measurement error as cause for common variance between personality factors
Personality Faking Situational demand Spurious measurement error
2009/12/16
The present article reanalyzed data collected by Toomela (2003). The data contain personality self ratings and cognitive ability test results from n = 912 men with military background. In his original...
Bayesian inference for an extended simple regression measurement error model using skewed priors
Berkson model non-informative prior non-random sample pseudo-Bayes factor regression calibration structural error model Winbugs
2009/9/22
In this paper, we introduce a Bayesian extended regression model
with two-stage priors when the covariate is positive and measured with error.
Connections are made with some results in Arellano-Vall...
