Journal of Business Research, 2015 AbstractIn marketing and finance, surprisingly simple models sometimes predict more accurately than more complex, sophisticated models. Here, we address the question of when and why simple models succeed — or fail — by framing the forecasting problem in terms of the bias–variance dilemma.

RoB 2: a revised tool for assessing risk of bias in randomised trials
British medical journal, 2019 Assessment of risk of bias is regarded as an essential component of a systematic review on the effects of an intervention. The most commonly used tool for randomised trials is the Cochrane risk-of-bias tool. We updated the tool to respond to developments

Research Synthesis Methods, 2020 Despite a major increase in the range and number of software offerings now available to help researchers produce evidence syntheses, there is currently no generic tool for producing figures to display and explore the risk‐of‐bias assessments that ...

Qualifying parabolic mirrors with deflectometry [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 Phase-measuring deflectometry is a full-field gradient technique that lends itself very well to testing reflective optical surfaces. In the past, the industry’s interest has been focussed mainly on the detection of defects and ripples, since it is easy ...

Salmon: fast and bias-aware quantification of transcript expression using dual-phase inference
Nature Methods, 2017 We introduce Salmon, a lightweight method for quantifying transcript abundance from RNA–seq reads. Salmon combines a new dual-phase parallel inference algorithm and feature-rich bias models with an ultra-fast read mapping procedure.

PSYCHOPHYSICS OF REMEMBERING: TO BIAS OR NOT TO BIAS? [PDF]
Journal of the Experimental Analysis of Behavior, 2010 Delayed matching to sample is typically a two‐alternative forced‐choice procedure with two sample stimuli. In this task the effects of varying the probability of reinforcers for correct choices and the resulting receiver operating characteristic are symmetrical.

ROBINS-I: a tool for assessing risk of bias in non-randomised studies of interventions
British medical journal, 2016 Non-randomised studies of the effects of interventions are critical to many areas of healthcare evaluation, but their results may be biased. It is therefore important to understand and appraise their strengths and weaknesses. We developed ROBINS-I (“Risk

Journal of the European Optical Society-Rapid Publications, 2019 Background Phase measuring deflectometry is a highly precise and full field metrology technique for specular surfaces based on the distortion of known reference patterns observed as a reflection at the surface under test.

International Journal of Epidemiology, 2015 Background: The number of Mendelian randomization analyses including large numbers of genetic variants is rapidly increasing. This is due to the proliferation of genome-wide association studies, and the desire to obtain more precise estimates of causal ...
