Data Mining Algorithms In R/Packages/CCMtools/CWGLI

Description edit

This 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 edit

CWGLI(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 edit

Value edit

Returns a numerical vector corresponding to the CWGLI cost function
