Dear all,

Does anyone know how to use function model_comparison to compute posterior odds ratios? I followed the method tanya advised as followed:

nomodels=2;

file_names = cell(nomodels,1);

file_names{1}=‘name1’;

file_names{2}=‘name2’;

model_priors = [1;1];

options_.model_comparison_approximation=‘Laplace’;

PosteriorOddsTable = model_comparison(file_names,model_priors);

but the system returns:

??? Input argument “options_” is undefined.

Error in ==> model_comparison at 51

if isfield(options_,‘model_comparison_approximation’)

Error in ==> comparison at 7

model_comparison(file_names,model_priors);

My Dynare edition is 4.2.0. I read the code of function model_comparison and found that this function needs five input, which are ModelNames,ModelPriors,oo,options_,fname. How to define oo and fname?

Many thanks.

Bob
