These parameters are the mean and standard deviation of the associated normal distribution, respectively.
The transfer function for a single mass-spring system under dynamic equilibrium, i.e. H (n) = σ d (n)/F (n) (where F (n), d (n) represent the acting force and standard deviation of displacement associated to the frequency n, respectively), is defined by Eq. (3)—see Gould and Abu-Sitta (1980).
The mean HR and the standard deviation of HR associated with ruminating were lowest of all the studied behaviour categories.
Using the linear levels of income-to-needs ratio, each 1-point difference (i.e., approximately 120% of a standard deviation) was associated with increased odds of attending ECEC at 18 months of 1.07, with the estimate only approaching statistical significance.
On the other hand, inconsistency in volume of the dispensed droplet is defined by the fraction of standard deviation associated with a set of dispensed volumes to their mean value.
The association was stronger for GI than GL, with approximately one standard deviation of GI intake associated with more than twice the increased risk associated with GL.
From this we have estimated that an increase in the Peabody picture vocabulary test scores at age 4 years of 0.25 of a standard deviation is associated with a 7.5% increase in income at age 30 (P=0.057), once we control for maternal ability scores.
Based on observational estimates, an increase in uric acid of one standard deviation was associated with hazard ratios for ischaemic heart disease of 1.55 (95% confidence interval 1.51 to 1.59) and 1.34 (1.28 to 1.39) in the Copenhagen General Population Study and Copenhagen City Heart Study, respectively.
An increase in Lenient towards cheating of one standard deviation is associated with a reduction in the self-certified sick leave rate of 0.27 percentage points.
Since our findings support the hypothesis of eGFR variability (measured by standard deviation) being associated with increased risk of dialysis or dialysis free death, the key message for clinicians or health policy makers is to consider using a simple statistic standard deviation, to assist in clinical care of CKD patients.
Both pairs of anatomical landmarks had the right ear as one of the references, which suggested that a possible systematic deviation was associated with the acquisition of the coordinates in B25.
