Nonparametric estimation of covariance functions by model selection [PDF]

open access: yes, 2009
We propose a model selection approach for covariance estimation of a stochastic process. Under very general assumptions, observing i.i.d replications of the process at fixed observation points, we construct an estimator of the covariance function by ...

A Multivariate Analysis of Covariance [PDF]

open access: yesBiometrics, 1958
of treatment effects increased with treatment duration, and because one of the variables which originally had been intended for use as a concomitant control was affected by treatments. No satisfactory form of analysis for dealing with these complications was reached, and the problems raised seem worth re-examining.
