An assessment of Bayesian bias estimator for numerical weather prediction [PDF]
Nonlinear Processes in Geophysics, 2008 Various statistical methods are used to process operational Numerical Weather Prediction (NWP) products with the aim of reducing forecast errors and they often require sufficiently large training data sets.

Inference in group sequential designs with causal mechanisms: implications for power and mediation analysis [PDF]
BMC Medical Research MethodologyBackground Group sequential designs are increasingly employed to allow trials to stop early with statistical rigor. While existing work focuses on intention-to-treat effect on clinical endpoints, the properties of mediation analysis (commonly conducted ...

Bias Corrected Estimation of Paleointensity (BiCEP): An Improved Methodology for Obtaining Paleointensity Estimates [PDF]
Geochemistry, Geophysics, Geosystems, 2021 Abstract The assumptions of paleointensity experiments are violated in many natural and archeological materials, leading to Arai plots which do not appear linear and yield inaccurate paleointensity estimates, leading to bias in the result.

Beta Kernel Estimator for a Cumulative Distribution Function with Bounded Support [PDF]
Journal of Sciences, Islamic Republic of Iran, 2023 Kernel estimation of the cumulative distribution function (CDF), when the support of the data is bounded, suffers from bias at the boundaries. To solve this problem, we introduce a new estimator for the CDF with support (0,1) based on the beta kernel ...

An Improved Codon Modeling Approach for Accurate Estimation of the Mutation Bias [PDF]
Molecular Biology and Evolution, 2021 Abstract Phylogenetic codon models are routinely used to characterize selective regimes in coding sequences. Their parametric design, however, is still a matter of debate, in particular concerning the question of how to account for differing nucleotide frequencies and substitution rates.

An own-age bias in age estimation of faces [PDF]
European Review of Applied Psychology, 2012 Abstract Introduction Age estimation performances may be influenced by group biases. Objective This study investigated whether we are more accurate at estimating the age of people from one's own-age than the age of younger or older people. Method Children, young and older adults’ performances at estimating both in-group and out-group faces ...

Synthesized randomized response techniques
Scientific African, 2023 Reducing response bias in survey research is important in ensuring that the data collected accurately represents the population of interest. This study proposes the synthesized random response technique (SRRT) estimator as an efficient method to reduce ...

Estimation of average treatment effect based on a multi-index propensity score
BMC Medical Research Methodology, 2022 Background Estimating the average effect of a treatment, exposure, or intervention on health outcomes is a primary aim of many medical studies. However, unbalanced covariates between groups can lead to confounding bias when using observational data to ...
