Data Mining Algorithms In R/Packages/CCMtools/WGP

Description
This function calculates the Weighted Global Probability (WGP) cost function for precipitation occurrence. This error is supposed to be due to a misclassification (i.e., the elements should be classified according to sequence cl.check, while they are in practice allocated to the clusters according to the sequence cl.proj).

Usage
WGP(cl.check, cl.proj, DataS.check)

Arguments

 * cl.check Reference sequence (i.e., numerical vector) of clusters.


 * cl.proj Sequence of clusters in practice.


 * DataS.check Precipitation data time series

Details
For details about this cost function, see the reference below. M. Vrac, P. Yiou. "Weather regimes designed for local precipitation modelling: Application to the Mediterranean bassin". Submitted, JGR-A, 2009

Value
Returns a numerical vector corresponding to the WGP cost function
