Hello, I'm new in R. I'm meteorological modeller and i will calculate some statistics for my model results. These statistis are the follow:
ANB: Average Normalized Absolute BIAS MNB: Mean Normalized BIAS MNE: Mean Normalised Error STDE: Standard Deviation of Error FB: Fractional BIAS MG: Geometric Mean BIAS VG: Geometric Variance SKVAR: Skill Variance RMSE: Root Mean Square Error NMSE: Normalized Mean Square Error r: Correlation Coefficient CV: Coeficient of Variation FAC2: Fractional Predictions within a factor of two of observations Hc: Hit Rate IOA: Index of Agreement Au: Unpaired Peak Concentration Accuracy As: Spatially-paired Peak Concentration Accuracy And their expressions are in the upload file: http://r.789695.n4.nabble.com/file/n2307880/Statistics.doc Statistics.doc I think that someone was developed this statistical functions for use in R, but if don't exist, someone help me to programme it?
