Joseph Berkson
Joseph Berkson (14 May 1899 – 12 September 1982) was trained as a physicist (BSc 1920 College of City of New York, M.A., 1922, Columbia), physician (M.D., 1927, Johns Hopkins), and statistician (Dr.Sc., 1928, Johns Hopkins).O'Fallon WM (1998). "Berkson, Joseph". Armitage P, Colton T, Editors-in-Chief. ''Encyclopedia of Biostatistics.'' Chichester: John Wiley & Sons. Volume 1, pp. 290-295. He is best known for having identified a source of bias in observational studies caused by selection effects known as Berkson's paradox. In 1950, as Head (1934–1964) of the Division of Biometry and Medical Statistics of the Mayo Clinic, Rochester, Minnesota, Berkson wrote a key paper entitled ''Are there two regressions?''. In this paper Berkson proposed an error model for regression analysis that contradicted the classical error model until that point assumed to generally apply and this has since been termed the Berkson error model. Whereas the classical error model is statistically independ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berkson's Paradox
Berkson's paradox, also known as Berkson's bias, collider bias, or Berkson's fallacy, is a result in conditional probability and statistics which is often found to be counterintuitive, and hence a veridical paradox. It is a complicating factor arising in statistical tests of proportions. Specifically, it arises when there is an ascertainment bias inherent in a study design. The effect is related to the explaining away phenomenon in Bayesian networks, and conditioning on a collider in graphical models. It is often described in the fields of medical statistics or biostatistics, as in the original description of the problem by Joseph Berkson. Examples Overview The most common example of Berkson's paradox is a false observation of a ''negative'' correlation between two desirable traits, i.e., that members of a population which have some desirable trait tend to lack a second. Berkson's paradox occurs when this observation appears true when in reality the two properties are unrelated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berkson Error Model
The Berkson error model is a description of random error (or misclassification) in measurement. Unlike classical error, Berkson error causes little or no bias in the measurement. It was proposed by Joseph Berkson in an article entitled “Are there two regressions?,” published in 1950. An example of Berkson error arises in exposure assessment in epidemiological studies. Berkson error may predominate over classical error in cases where exposure data are highly aggregated. While this kind of error reduces the power of a study, risk estimates themselves are not themselves attenuated (as would be the case where random error Observational error (or measurement error) is the difference between a measured value of a quantity and its true value.Dodge, Y.
