BLRPM.OF
is the objective function used for parameter estimation of the BLRPM parameters.
Given a set of BLRPM parameters par
this function calculates a set of model statistics at
given accumulation time steps acc.vals
. These model statistics are compared with given
time series statistics stats
in the objective function. The user is able to define weights
for each statistic (has to be the same length as statistics input vector). Option for debugging is given.
A scale
parameter defines a criterium for which different kinds of model statistics are calculated.
This criterium is mainly based on the timescale difference between storm duration parameter gamma and cell duration
parameter eta.
If use.log
is true, the objective function needs logarithmic input parameters. The value
of OF
defines the kind of objective function to be used: 1= quadratic 2= quadratic extended 3= absolute 4= absolute extended.
