# Data Mining Algorithms In R/Packages/CCMtools/CWGLI

## Description

editThis function calculates the Conditional Weighted Global Log-Intensity (CWGLI) cost function for precipitation. 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

editCWGLI(cl.check, cl.proj, DataS.check)

## Arguments

edit- cl.check Reference sequence (i.e., numerical vector) of clusters (i.e., this is the sequence we should have).

- cl.proj Sequence of clusters in practice.

- DataS.check Precipitation data time series

## Details

editFor 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

editReturns a numerical vector corresponding to the CWGLI cost function
