I built a simple one-stage model using a script (see below), but I wasn't able to add a validation data set to the testplan, in order to obtain the validation RMSE. How can I do this?

I saw this: http://au.mathworks.com/help/mbc/examples/gasoline-case-study-design-of-experiment.html?prodcode=MB&language=en, but they just make another data set, and do not use it for validation (to obtain the validation RMSE).

%%Create a New mbcmodel Project
project = mbcmodel.CreateProject;
%%Load Data into Project
load SobolSequence                       
data = mbcmodel.CreateData;
S = ExportToMBCDataStructure(data);
S.varNames = {'p_im','omega_e','eta_vol'};
S.data = [SobolSequence(:,1),SobolSequence(:,2),SobolSequence(:,3)];
S.varUnits = {'Pa', 'rad/s', '-'};
S.comment = 'Imported from mat data';
data = BeginEdit(data);
data = ImportFromMBCDataStructure(data , S);
data = CommitEdit(data);
%%Build Test Plan 
% Define Inputs for test plan.
LocalInputs = mbcmodel.modelinput('Symbol',{'p_im','omega_e'},'Name', ...
                           {'p_im','omega_e'}, ...
                           'Range',{[1.02e5 2.32e5],[157 262]});
% Create test plan.
testplan = CreateTestplan( project, {LocalInputs} );
% Attach data to the test plan.
AttachData( testplan, data );      
%Model = mbcmodel.CreateModel('RBF',LocalInputs);
LocalModel = testplan.DefaultModels;
CreateResponse(testplan,'eta_vol');
response = testplan.Responses(1)
SummaryStatistics(response);

Hi Bas,

MBC command-line does not have this capability at the moment. I have taken a note of your request so that we can add this functionality in a future release. For now, you will need to load the validation data into MATLAB and then calculate model predictions and validation RMSE.
