Sex proportion as a covariate increases the statistical test power in growth performance based experiments using as-hatched broilers.

open access: yesPLoS ONE, 2023
The availability of sexed day-old broiler chicks is becoming an issue as feather sexing is no longer possible. This has great implications for broiler researchers as the use of randomly distributed mixed-sex birds may result in a greater between-pen ...

Global testing under sparse alternatives: ANOVA, multiple comparisons and the higher criticism [PDF]

open access: yes, 2010
Testing for the significance of a subset of regression coefficients in a linear model, a staple of statistical analysis, goes back at least to the work of Fisher who introduced the analysis of variance (ANOVA).

Calibration of Computational Models with Categorical Parameters and Correlated Outputs via Bayesian Smoothing Spline ANOVA [PDF]

open access: yes, 2014
It has become commonplace to use complex computer models to predict outcomes in regions where data does not exist. Typically these models need to be calibrated and validated using some experimental data, which often consists of multiple correlated ...
