Excluding all observations greater than a specified cut-off value is the second option.
Subsequent statistical tests were carried out for the duck samples using GeneSpring 7.2 (Silicon Genetics) to determine all genes differentially regulated to a specified cut-off value (p = 0.05).
Outliers were identified following the guidelines devised by Kosnik and Kaufman (2008); regression analysis was performed (using Matlab version 7.10.0), and data-points with residuals above or below a specified cut-off point were regarded as outliers.
A statistical test is used to estimate a p value and a specified cut-off is chosen, such that below it protein changes are deemed significant.
% = percentage of infants with antibody concentrations above the specified cut-off.
The remaining 67 participants were used to calculate the window periods corresponding to specified cut-off values and to calculate cut-off values corresponding to specified window periods.
Not all studies specified cut-offs for major depression and none specified cut-offs for clinical anxiety, suggesting that precise prevalence estimates may not be available.
24 Logistic regression models provide estimates of survival at specified "cut-off points".
However, they do not provide quantified expression profiles for genes identified as differentially expressed under a specified statistical cut-off.
If C falls below a user-specified cut-off, then the ROI is rejected from the target list.
The World Bank has proposed a similar definition but has not specified a cut-off value [ 81].
