When changes over time are gradual (as during silvicultural conversion of even-aged, second-growth forests to an uneven-aged condition) and resources are limited, power analysis helps allocate sampling effort to maximize the probability of detecting small effect sizes.
QuickFix computes the static routes using the sub-gradient method, and based on QuickFix, SnapIt adaptively allocates sampling rate for a single node with a possibly dynamic recharging rate.
While the pollution source indicators used to allocate sampling sites were consistent with the LUR literature, we did not find strong overall relationships between measured pollutants and traffic density or emissions-weighted proximity to industry.

Following this, we allocated sample numbers according to the population distribution of each county.
The null distribution for this score was assessed by simulations in which we repeatedly allocated samples to HPV groups at random.
We analyzed all parametric data of allocated samples based on the intention-to-treat model.
A consecutive sampling method was then employed to select eligible cases and controls until the allocated sample size was filled from the respective health facilities.
Each short term family planning user who was visiting selected health centers during the study period were interviewed until the allocated sample size to every facility was reached.
The study participants were selected every eight (8th) household intervals, by dividing the total number of households to the allocated sample size.
The stratification was done during the selection and where randomly selected number of patients in a stratum got at least half of the allocated sample size the subsequent random selections will only be valid if is for the other stratum.
