object of class cardiFit returned by fitweibull6 or
fitweibull4 or parameter vector of the fitted Weibull function,
xmin
left boundary (in day of year) of the integral under the curve,
xmax
right boundary (in day of year) of the integral under the curve,
quantile
two-sided quantile (percentage of integral)
which defines beginning and end of the peak,
symmetric
if (TRUE), quantiles are calculated for the whole area
under the curve, otherwise for each of the branches separately.
Details
CDW is a numerically improved version of the algorithm
described in Rolinski et al. (2007). Version CDWa is an alternative,
simplified version which sets the baseline before and after the peak to zero
using appropriate offset parameters p[1] and p[4].
The original method described by Rolinski et al. 2007 (here called CDW)
shifts the function for the left and right branch separately
in the asymmetric case.
