Background: One of the challenges with modeling the temporal progression of biological signals
is dealing with the effect of noise and the limited number of replicates at each time point. Given the
rising interest in utilizing predictive mathematical models to describe the biological response of an
organism or analysis such as clustering and gene ontology enrichment, it is important to determine
whether the dynamic progression of the data has been accurately captured despite the limited
number of replicates, such that one can have confidence that the results of the analysis are
capturing important salient dynamic features.
Results: By pre-selecting genes based upon quality before the identification of differential
