GOF

Description

Good of fitting

Usage

GOF(Y_obs, Y_sim, w, include.r = TRUE, include.cv = FALSE)

Arguments

Y_obs	Numeric vector, observations
Y_sim	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.
include.r	If true, r and R2 will be included.
include.cv	If true, cv 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

Examples

Y_obs = rnorm(100)
Y_sim = Y_obs + rnorm(100)/4
