Truncated tests for combining evidence of summary statistics

Genetic Epidemiology, 2020
AbstractTo date, thousands of genetic variants to be associated with numerous human traits and diseases have been identified by genome‐wide association studies (GWASs). The GWASs focus on testing the association between single trait and genetic variants.

Truncation, statistical inference, and single-particle description

Physical Review C, 1987
A generalization of the time dependent Hartree-Fock approach is presented. The corresponding extension is made by recourse to standard tools of statistical mechanics and allows for a wider scope of applications in comparison with the conventional treatment.

Linear rank statistics for truncated data

Biometrika, 1990
SUMMARY Motivated by Prentice's (1978) generalization of linear rank statistics for censored data, we introduce a similar kernel for deriving linear rank statistics for truncated data. They take very similar forms to those of Prentice's statistics. Moreover, we also show that they can be expressed equivalently in weighted log rank-type forms, thus ...

Statistical characteristics of the truncated Wilson distributions

Acta Crystallographica Section A Foundations of Crystallography, 1993
Theoretical expressions are derived for 〈yn〉, n = 1 to 8, 〈(z −1)n〉, n = 2, 3 and 4, 〈(z − 〈z〉)n)〉, n = 2, 3 and 4, 〈|z − 1|〉, 〈|z − 1|3〉 and 〈|z − 〈z|3〉, where y is the normalized structure-factor magnitude and z (= I/〈I〉) is the normalized intensity, valid for the centric and acentric Wilson distributions truncated such that a1/2 ≤ y ≤ b1/2.

Effects of Spectral Truncation on Photocount Statistics

Journal of Applied Physics, 1972
For many photocounting experiments, it is desirable to know the theoretical photocount distribution for radiation whose spectral shape may be altered by an optical filter or truncated in some manner. The effect of spectral truncation (band limiting) is investigated by computing the photocount distribution by a method that makes direct use of the power ...

Some Useful Statistical Methods for Truncated Data

Journal of Quality Technology, 1992
Truncated data arise when a variable is observable only over some portion of its range. This paper describes how truncated data arise in studies of the field performance or reliability of manufactured items. Failure to account for truncation can lead to..

Statistical Evaluation of Truncated Breath-Alcohol Test Measurements

Journal of Forensic Sciences, 1988
Abstract The reporting of breath-alcohol measurements truncated to two decimal places is a form of computational error. The magnitude of the error can range from 0.000 to 0.009 g/210 L. The truncation error will follow a uniform distribution.

Prediction from Truncated Payment Statistics

1990
Payment statistics involve numbers and totals of payments at specified times or time intervals. The accuracy and detail in amount and time specifications vary with the application, and different specifications lead to different kinds of estimation and prediction problems. The purpose here is to show that estimation and prediction problems for truncated

Truncated exponential frequency-magnitude relationship in earthquake statistics

Bulletin of the Seismological Society of America, 1977
abstract The following doubly truncated exponential probability density distribution f ( M ) = β exp ⁡ { − β ( M − M 0 ) } / { 1 − exp ⁡ { − β ( M p − M 0 ) } } for M 0 ≦ M ≦ M p f ( M ) = 0 for M ≧ M p , ( a ) where M0 is the threshold magnitude value, and β is a parameter, is proposed for the earthquake ...
