The ratios of coverage between genomes from different species or strains/subspecies in an ecosystem sample span a continuum, unlike the quantized levels of coverage determined by ploidy or repeat copy-number differences.
All genes were detected by rt-PCR in each sample, whereas by microarray the samples showed a continuum of detection frequency.
Four practices and their consequences are considered: limited sampling of a continuum, turning continuous predictors into categories through dichotomization and similar practices, treating continuous predictors as categorical in an analysis, and overuse of the analysis of variance.
Our sample therefore captured a continuum of weight gain for contrasting body morphologies and thereby represents a wide range of body shape variation among African populations.
Word frequency ratings were based on the Zeno et al. (1995) Standard frequency index (SFI); stimuli sampled an SFI continuum from 40.0 to 75.0 relatively evenly (unit = log-transformation of a weighted frequency per million).
Relationships between the statistical properties of a mixture, the variance in concentration among a number of samples taken from the mixture, and the size and geometry of the samples are considered, using a continuum model.
Considering visualization and statistic analysis we suggest the following interpretation: the data set represents one core cluster of the most metabolically sound samples (cluster 3 on Figure 1) and a continuum of samples extended in one direction, like a head and a tail of a comet.
To determine the major trends across the samples we conducted principal component analysis (PCA) that highlighted the uniqueness of the merozoite samples, clustering them approximately half-way on a continuum between the tachyzoite/bradyzoite and oocyst samples.
Since the biology between subtypes is a continuum and some samples may have close proximity to more than 1 prototypic subtype, we used a Monte-Carlo simulation to introduce random error into the call to determine the frequency of switching subtype [ 26].
The differences in the distributions may also represent a continuum that with increased sampling within the teleostei infraclass, particularly of those species intermediate to those presented here, would fill the gap.
