Stress Testing of Consumer Credit Default Probabilities Using Panel Data (Error using categorical/ismember (line 48))

Hi all,

I am trying to use the code in "Stress Testing of Consumer Credit Default Probabilities Using Panel Data" on data I have.

I formatted the data in the same way as the data given as an example. However I get the following error

Error using categorical/ismember (line 48)
Categorical inputs to ISMEMBER must both be either ordinal or not ordinal.

Error in classreg.regr.modelutils.designmatrix>convertVar (line 504)
        [tf,loc] = ismember(a,b);

Error in classreg.regr.modelutils.designmatrix>dummyVars (line 446)
    group = convertVar(group,glevels); % convert group to be compatible with glevels

Error in classreg.regr.modelutils.designmatrix (line 290)
            [Xj,dummynames] = dummyVars(dummyCoding{j},Xj,catLevels{j});

Error in classreg.regr.CompactTermsRegression/designMatrix (line 142)
                    = classreg.regr.modelutils.designmatrix(X,'Model',terms(:,varLocs), ...

Error in classreg.regr.CompactGeneralizedLinearModel/predict (line 271)
            design = designMatrix(model,Xpred);

Error in GeneralizedLinearModel/predict (line 394)
                    [e-mail]Model(model,Xpred,varargin{:});

I could not figure out what I am doing wrong.

Thanks in advance for the help
