The 3-day moving average population-weighted concentrations of ambient carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), and particulate matter less than 2.5 microns in diameter (PM2.5) were calculated using measurements from stationary monitors from January 1st, 1999 December 31st , 20099 [ 4].
CHART: Change in retail sales from January 2003: 3-month moving average, adjusted for seasonal variation, population growth and inflation, shown in 2009 dollars; Building materials: stores Peaked in early 2006, with housing prices.; Computer stores: When the Nintendo Wii was released, sales at computer stores soared.
Figure 1A shows the time trends of ASIRs of mesothelioma in the Hong Kong general population, based on the centered moving average method with a 5-year interval.
Models for hospital admission analysis in the warm season included the moving average of total admission counts (ICD 9: <800) to offset population reduction during the summer holidays.
Cell values were derived using a weighted moving average function (Burrough, 1986), and then calculated based on known population by state.
Raw monthly prescription volumes exhibit seasonal and safety net fluctuations [ 27], so they are smoothed (using a moving average over non-zero values) and then normalised by the population growth in Australia to give the number of prescriptions per 100,000 Australians.
Cell values were derived using a weighted moving average function (Burrough, 1986, 153) and then calculate based on known population by state.
The Surveillance Tree method was found to be at least as effective as a univariate, exponentially weighted moving average (EWMA) control chart when increases occurred in a subgroup of the monitored population.
The decline of LD with distance behaved as expected, with the moving average following the predicted LD curve based on the estimate of the historical effective population size.
Because the basic area unit of one square kilometer was too small for statistical analysis of geographical distribution, the moving average of nine grid squares as well as a "combined grid square method" based on population density was used.
Three and five-day moving averages of primary OC in PM exposure effects on IL-6 blood levels in elderly susceptible populations have also been reported in previous studies and appeared more pronounced than 1-day moving average exposures [ 41].
