Sentence examples for variance measurements from inspiring English sources
Scanning electron microscope images are used to correlate grooving methods with coefficient of friction and shear force variance measurements.
Our results show that variance measurements based on fewer than 20 measurements are generally unreliable and ideally more than 50 measurements are required to reliably compare variances with less than a 2-fold difference.
We have developed an analysis of the standard error of variance from a sample of size n, and we have defined error bars for variance measurements based on this standard error.
These variance measurements have been made with samples of quite modest size, which should be a source of concern because higher-order statistics, such as variance, are poorly estimated from small sample sizes.
We compare variance measurements from human clinical data and from mouse models and show that the mutation level variance is clearly higher in the human data than it is in the mouse models at both the primary oocyte and offspring stages of inheritance.
For each cell/object identified, average and total intensity and intensity variance measurements were taken.
Our main variance measurement is therefore the mean measured variance of the gene across the four species, which is calculated as described in Methods.
MLE algorithm depicted in Algorithm 1 was applied to the measured respiratory signals, and the resulting measurement noise variance, measurement noise shape factor, and parameter convergence tracks were plotted.
Different allocations of biological and technical replicates were evaluated by minimizing the variance of the ratio of technical variance (measurement error) to the total variance (sum of sampling error and measurement error).
While all are able to achieve a sub-SNL phase variance measurement in the lossless case, for the choice of a coherent and squeezed vacuum input state, all are outperformed by a homodyne measurement when loss is introduced.
The comparable metric for our variance measurement was 91% (Additional File 1, Supplemental Methods 3).
