This paper provides an alternative test procedure for the problem of testing normal mean against two-sided alternative with known variance for costly trials.
Thus, alternative testing procedures using laboratory animals have been proposed for quality control of these products.
Several methods have been proposed to account for the selection problem when missing data are non-ignorable, including the use of longitudinal data [ 7, 8, 11] and alternative testing procedures [ 12]; however these approaches are not applicable to existing cross-sectional datasets, such as the DHS.
The ultimate goal of this study was to determine whether the VecTest assay could serve as a suitable alternative testing procedure for WNV dead bird surveillance.
Generally speaking, the weighted Simes test has power advantages over alternative weighted test procedures if the effect sizes are of similar magnitude.
We may then consider the following, alternative, LOCAL test procedure.
As an alternative, we suggest that nonparametric test procedures are much more powerful because they are distribution-free and statistical power to reject the null is positively related to number of observations in the time series and accuracy, rather than precision, of point estimates of metrics (Sokal and Rohlf 1995).
Typically, in the conventional validation procedures for an alternative test method, a sequential approach to the process is taken.
An alternative survival-adjusted test procedure based on isotonic regression methodology has previously been proposed.
Be that as it may, one thing is certain--this is a golden opportunity for the development, validation, and application of alternative test methodologies and testing strategies, namely, procedures that do not rely on the use of laboratory animals.
