crwtransform: Method crwtransform: returns the centers and the radii of bins of a distribution
Description
Centers and ranges calculation for bins of a histogram. It is useful for a
very fast computation of statistics and methods based on the L2 Wassertein
distance between histograms.
Usage
crwtransform(object)
# S4 method for distributionH
crwtransform(object)
Value
A list containing
$Centers
The midpoints of the bins of the
histogram
$Radii
The half-lenghts of the bins of the histogram
$Weights
The relative frequencies or the probailities associated with
each bin (the sum is equal to 1)
Arguments
object
a distributionH object
