Female mice exhibit less overall variance, with a higher proportion of structured variance, than males at multiple timescales of continuous body temperature and locomotive activity records

Biology of Sex Differences, 2022
Highlights Female mice do not show more overall variance in temperature or activity than do males. When measuring rodents, phase of the daily rhythm accounts for a substantial amount of the overall variance.

Using photographs for rating severity degrees of clinical appearance in research mice enables valid discrimination of extreme but not mild and moderate conditions: A pilot study.

PLoS ONE, 2023
To ensure good animal welfare in laboratory research and in stockbreeding severity ratings of the animals´ wellbeing are essential. The current study investigated how valid raters can evaluate different severity degrees of clinical appearance and how ...

Estimation of genetic variation in residual variance in female and male broiler chickens [PDF]

, 2008
In breeding programs, robustness of animals and uniformity of end product can be improved by exploiting genetic variation in residual variance. Residual variance can be defined as environmental variance after accounting for all identifiable effects.

The Mean-Variance Model Revisited with a Cash Account [PDF]

Journal of Mathematical Finance, 2012
Fund managers usually set aside a certain amount of cash to pay for possible redemptions, and it is believed that this will affect overall fund performance. This paper examines the properties of efficient portfolios in the mean-variance framework in the presence of a cash account.

An update on modeling dose-response relationships: Accounting for correlated data structure and heterogeneous error variance in linear and nonlinear mixed models.

Journal of Animal Science, 2016
Advanced methods for dose-response assessments are used to estimate the minimum concentrations of a nutrient that maximizes a given outcome of interest, thereby determining nutritional requirements for optimal performance.

Accounting for geographical variance in the union satisfaction gap

Industrial Relations Journal, 2019
AbstractEvidence of spatial variance in the relationship between trade union membership and job satisfaction is limited. Using three nationally representative data sets, we examine lower levels of satisfaction among union members and considers how this relationship varies geographically across the nations and regions of Great Britain.
