High variance and Moments NaN (variance decomposition)

Postby killergabin » Fri Feb 22, 2013 6:41 am

Hello everyone,

I'm running a model, everything seems good but I receive bad results: theoretical moments have high or NaN std and variance. Thus I have bad variance decomposition.

Any idea of what's wrong?

Hi,

Run your model ones and then type: model_diagnostics(M_,options_,oo_). The message says you have one co-linear relationship, it also gives you the equations where this colinearity is coming from. Make sure that your model is well defined.
