In addition, only the constancy, the difference between the indicated and true activity of the calibration source, was used in the statistical analysis.
It is noteworthy that the sequences labeled TR2 in the teleost lineage are two residues shorter than teleost and tetrapod TR1 and tetrapod TR2, which are the same length (Fig. 4C), supporting a difference in the requirement for sequence constancy between the two lineages, but it is unclear how this relates to the potential gene duplication events.
As above, models including a term for the interaction between treatment and time will be fit to assess the constancy of the difference between groups over time.
Our main findings were (a) the constancy of the relationship between tumour size and nodal involvement, (b) no significant differences in the relationship between tumour size and the 5-year risk of distant metastases for IGR 1954 1983 and SG 1976 1990 and (c) a change in this relationship after 1990 in the Stockholm database.
Using this program, the average expression stability value M (defined as the constancy of the expression ratio between two reference genes across samples) for each gene was obtained in a stepwise fashion excluding the gene with the highest M for the next calculation round.
In this study we present a methodology based upon permutation test analysis of SAGE data, to identify reference genes that more stringently satisfy the constancy requirements crucial for accurate normalization between samples utilized in gene expression experiments.
Additionally, we observed only nine (3.9%) authors discussed the constancy assumption and there was no difference in this respect between trials that were published in high-impact or low-impact journals.
Linearity between the system's input and output, as well as the constancy of the parameters (time-invariance), simplify the mathematical models.
Writing was the constancy".
And that's something, the constancy of the man".
