Concentrations of serum cholesterol, LDL-C, HDL-C and triglyceride were not normally distributed, and were presented as geometric means with an approximate standard deviation.
The approximate standard deviation of each threshold value was estimated by calculating the standard deviation of the average of each consecutive pair of reversal points (one peak and one valley) (Wetherill and Levitt, 1965).
For effectiveness factor, an approximate analytical expression, with a maximum deviation of less than 1.5% from analytical solutions or numerical calculation results, is proposed for arbitrary kinetics.
Similarly, the population size of the resistant bacteria, (R t)), gets a maximum standard deviation at (t=0.915) with an approximate value of 1.10.
Based on the primary variable of this study, which is the mean change in ACQ-5 score from baseline level, we determined a sample size of about 1000 patients in the entire Asian region to give us a 95% confidence interval (CI) with an approximate width of 0.12 units when standard deviation (SD) is 1.0 unit.
The residual can be considered a prediction error of X m,n) by its neighboring data, and the median operation over the residuals as Equation (7) gives approximated standard deviation of data.
To detect OFF periods, we combined all multi-unit and single-unit activity on a single channel into a point process representation, and then smoothed with a Gaussian kernel with a standard deviation of 20 ms to approximate an instantaneous firing rate in the units surrounding that electrode.
When we take a standard deviation of 0.15 as an approximate quantitative criterion (95% normal confidence interval, allowing a four-fold variation in expressions induced by amplification), for 39% of the genes the variation in the gene expression introduced by amplification was outside this confidence interval.
