Samples of measurement clusters with and without fluctuation per SAIF Definitions 1 and 2 are shown in Table 1 (Additional file 1).
In the following, we are considering two biological conditions with different outcomes, with n1 samples of expression measurements of p genes (that form a gene set) for the first, and n2 samples of measurement of the same p genes for the second conditions.
A statistical validation of the numerical results is not yet possible due to the relatively small sample of measurements at hand.
By combining light fluorescent microscopy and EM, we have obtained by far the greatest sample of measurements of N/E-ergic vesicles in mammalian CNS to date.
The t test that looks at the mean and variance of a sample of measurements was then used to discover collocations.
Obviously, repetition of the experiment as perceived by the biologist consists in taking a new sample of subjects (e.g. patients) and taking a new sample of measurements from these subjects, as described in Equations (3) or (5).
Baseline characteristics, clinical history and serial blood samples for measurements of thyroid hormones were collected.
Blood samples for measurements of DNA-PK activity were collected from April 2002 to August 2005.
Blood samples for measurements of coagulation variables were taken daily for the following 3 days.
Weight of the sample for measurements of sulfur isotope composition was 400 μg as Ag2S, and 360 μg as BaSO4.
Six patients were subsequently excluded from analysis for lack of blood samples for measurement of FGF23.
