Data Enlargement
Description
Enlargement of data which is too short for a surveillance method to evaluate.
Usage
enlargeData(disProgObj, range = 1:156, times = 1)
Arguments
disProgObj |
object of class disProg (including the observed and the state chain). |
range |
range of already existing data (state , observed )
which should be used for enlargement. |
times |
number of times to enlarge. |
Details
observed
and state
are enlarged in the way that the part range
of observed
and state
is repeated times
times in front of observed
and state
.
Sometimes it's useful to care for the cyclic property of the timeseries, so as default
we enlarge observed and state once with the first three existing years, assuming a year
has 52 weeks.
Value
disProg |
a object disProg (disease progress) including a list of the observed
and the state chain (extended with cyclic data generation) |
