Variance Minimization – Relationship between Completion-Time Variance and Waiting-Time Variance [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1996
AbstractThe completion-time variance (CTV) and the waiting-time variance (WTV) are two performance measures which are commonly used in optimization of single-machine scheduling systems. This paper shows that when the number of jobs is large the two measures are nearly equivalent in a probabilistic environment.

Getting Around Cosmic Variance [PDF]

open access: yes, 1997
Cosmic microwave background (CMB) anisotropies probe the primordial density field at the edge of the observable Universe. There is a limiting precision (``cosmic variance'') with which anisotropies can determine the amplitude of primordial mass ...

Selective increases in inter-individual variability in response to environmental enrichment in female mice

open access: yeseLife, 2018
One manifestation of individualization is a progressively differential response of individuals to the non-shared components of the same environment. Individualization has practical implications in the clinical setting, where subtle differences between ...

Variance Spectroscopy

open access: yesThe Journal of Physical Chemistry Letters, 2015
Spectroscopic analysis and study of nanoparticle samples is often hampered by structural diversity that presents a complex superposition of spectral signatures. By probing the spectra of small volumes within dilute samples, we can expose statistical variations in composition to obtain information unavailable from bulk spectroscopy. This new approach is

Testing jointly for structural changes in the error variance and coefficients of a linear regression model [PDF]

open access: yes, 2019
We provide a comprehensive treatment for the problem of testing jointly for structural changes in both the regression coefficients and the variance of the errors in a single equation system involving stationary regressors.
