Cramer von Misses

Description

Function to compare the observed and predicted distribution using the Cramer von Misses index.

Usage

measure.cm(
  indexObs = NULL,
  indexPrd = NULL,
  obs = NULL,
  prd = NULL,
  dates,
  Nbins = 100,
  what = c("CvM", "pval", "KSdiff"),
  threshold = NULL
)

Arguments

indexObs	index computed from the observations
indexPrd	index computed from the predictions
obs	A vector of observations
prd	A vector of predictions
dates	dates
Nbins	Number of bins used for discretization. Default to 100.
what	Measure to be returned. This can be the Cramer von Misses index ("CvM"), the p-value ("pvalue") of the test or the maximum absolute difference between the observed and predicted distributions ("KSdiff"). Default to "CvM".
threshold	Optional. Numeric value indicating the threshold above which to compute the measure. Mainly used for precipitation, tipically to use only the wet days in the analysis (i.e.: threshold = 1).

Value

A floating number with the measure indicated in what argument.
