A Baseline DSGE Model-----an error

The model is based on the Baseline DSGE model of Jesus Fernandez.And I add three equations ans three variables.there are the following errors.

You did not declare endogenous variables after the estimation command.

If anyone knows how it happened ,please let me know. Thanks a lot.BaselineDSGE_steadystate.m (2.65 KB)BaselineDSGE_steadystate.m (2.65 KB)

You defined yd_f as an observable, but the variable in the data-file is named y_f.
