gofRMSE: Root Mean Square Error
In ehaGoF: Calculates Goodness of Fit Statistics

Description Usage Arguments Value Author(s) References Examples

Calculates and returns root mean square error (RMSE).

1	gofRMSE(Obs, Prd, dgt = 3)

`Obs`	Observed or measured values or target vector.
`Prd`	Predicted or fitted values by the model. Values produced by approximation or regression.
`dgt`	Number of digits in decimal places. Default is 3.
