ValidationRMSE

Calculates the validation RMSE for model data

Syntax

s = ValidationRMSE(model,X,Y)

Description

s = ValidationRMSE(model,X,Y) calculates the root mean squared error (RMSE) of a validation set.

Input Arguments

model — Model object

mbcmodel.model object

Model whose root mean squared error is being computed, specified as a mbcmodel.model object.

X, Y — Validation data

table object | numeric array

Validation data to calculate RMSE, specified as a table object or numeric array.

Output Arguments

s — RMSE error

array

Root mean squared error of the model compared to the validation set.
