Error occur when estimate parameter

When estimate parameters of a basic linearized NK model,
dynare keep warning me the jaccobi contains NaNs,
and I don’t know how to correct.

codes and data are in attachments
NK_4_obs.m (432 Bytes)
NK_4.mod (777 Bytes)

Please follow Remark 2 (Using stoch_simul before Estimation) from Pfeifer(2013): “A Guide to Specifying Observation Equations for the Estimation of DSGE Models” sites.google.com/site/pfeiferecon/Pfeifer_2013_Observation_Equations.pdf.

That way, you would have recognized that you did not set i_ss and delta.
