Bias Correction of ML and QML Estimators in the EGARCH(1,1) Model [PDF]

n this paper we derive the bias approximations of the Maximum Likelihood (ML) and Quasi-Maximum Likelihood (QML) Estimators of the EGARCH(1,1) parameters and we check our theoretical results through simulations.

Micro-bias and macro-performance

, 2008
We use agent-based modeling to investigate the effect of conservatism and partisanship on the efficiency with which large populations solve the density classification task--a paradigmatic problem for information aggregation and consensus building.

Molecular Bias

European Journal of Epidemiology, 2005
Bias is ubiquitous in research. The advent of the molecular era provides a unique opportunity to study the consequences of bias with large-scale empirical evidence accumulated in the massive data produced by the current discovery-oriented scientific effort, rather than just with theoretical speculations and constructs.

Laser-tracker-based reference measurement for geometric calibration of phase-measuring deflectometry with active display registration [PDF]

Journal of Sensors and Sensor Systems
Phase-measuring deflectometry (PMD) with active display registration (ADR) is a ray-optics-based technique for the shape measurement of specular surfaces.

Improvements in Maximum Likelihood Estimators of Truncated Normal Samples with Prior Knowledge of σ [PDF]

Researchers analyzing historical data on human stature have long sought an estimator that performs well in truncated-normal samples. This paper reviews that search, focusing on two currently widespread procedures: truncated least squares (TLS) and ...

The optimism bias [PDF]

Current Biology, 2011
SummaryThe ability to anticipate is a hallmark of cognition. Inferences about what will occur in the future are critical to decision making, enabling us to prepare our actions so as to avoid harm and gain reward. Given the importance of these future projections, one might expect the brain to possess accurate, unbiased foresight.

Effects of Short-Term Laser Beam Heating on the Absorptivity of Steel Sheets

Journal of Manufacturing and Materials Processing, 2019
The efficiency of laser beam processes basically depends on the efficiency of the laser beam source and the efficiency of the irradiated material’s energy absorption. This absorptivity can be influenced by the surface condition.

Constraints on Assembly Bias from Galaxy Clustering

, 2016
We constrain the newly-introduced decorated Halo Occupation Distribution (HOD) model using SDSS DR7 measurements of projected galaxy clustering or r-band luminosity threshold samples.
