Simple moving average 6 model (SMA94): The numbers of
patients for each hour of 1994 were used to generate
unweighted moving average models. This was done by
calculating the mean of each data value taken together
with an equal number of points before and after the
original value. This yields a progression of time series
variables of increasing smoothness as more terms are
included in the moving averages. Models using one
through five data points on either side of the target value
were constructed.
