The analysis of very small samples of repeated measurements II: a modified box correction [PDF]
, 2010 There is a need for appropriate methods for the analysis of very small samples of continuous repeated measurements. A key feature of such analyses is the role played by the covariance matrix of the repeated observations.

Derivative Computations and Robust Standard Errors for Linear Mixed Effects Models in lme4 [PDF]
, 2017 While robust standard errors and related facilities are available in R for many types of statistical models, the facilities are notably lacking for models estimated via lme4.

Permutation inference methods for multivariate meta-analysis
, 2019 Multivariate meta-analysis is gaining prominence in evidence synthesis research because it enables simultaneous synthesis of multiple correlated outcome data, and random-effects models have generally been used for addressing between-studies ...

Sophisticated sperm allocation in male fowl [PDF]
, 2003 When a female is sexually promiscuous, the ejaculates of different males compete for the fertilization of her eggs; the more sperm a male inseminates into a female, the more likely he is to fertilize her eggs.

Optimal mapping of terrestrial gamma dose rates using geological parent material and aerogeophysical survey data [PDF]
, 2012 Regulatory authorities need ways to estimate natural terrestrial gamma radiation dose rates (nGy h−1) across the landscape accurately, to assess its potential deleterious health effects. The primary method for estimating outdoor dose rate is to use an in

Trade-offs between personal immunity and reproduction in the burying beetle, N. vespilloides [PDF]
, 2014 We know that parental investment and immune investment are costly processes, but it is unclear which trait will be prioritised when both may be required.

A genome-wide association study demonstrates significant genetic variation for fracture risk in Thoroughbred racehorses [PDF]
, 2014 Background: Thoroughbred racehorses are subject to non-traumatic distal limb bone fractures that occur during racing and exercise. Susceptibility to fracture may be due to underlying disturbances in bone metabolism which have a genetic cause.

Information Splitting for Big Data Analytics
, 2016 Many statistical models require an estimation of unknown (co)-variance parameter(s) in a model. The estimation usually obtained by maximizing a log-likelihood which involves log determinant terms. In principle, one requires the \emph{observed information}
