GOF

Description

Good of fitting

Usage

NSE(yobs, ysim, w, ...)

KGE(yobs, ysim, ...)

GOF(yobs, ysim, w, include.cv = FALSE, include.r = TRUE)

Arguments

yobs	Numeric vector, observations
ysim	Numeric vector, corresponding simulated values
w	Numeric vector, weights of every points. If w included, when calculating mean, Bias, MAE, RMSE and NSE, w will be taken into considered.
...	ignored
include.cv	If true, cv will be included.
include.r	If true, r and R2 will be included.

Value

• RMSE root mean square error

• NSE NASH coefficient

• MAE mean absolute error

• AI Agreement index (only good points (w == 1)) participate to calculate. See details in Zhang et al., (2015).

• Bias bias

• Bias_perc bias percentage

• n_sim number of valid obs

• cv Coefficient of variation

• R2 correlation of determination

• R pearson correlation

• pvalue pvalue of R
