Hi, i have dsge model in dynare that is running.but model diagnostics say it contains unit root.and i dont know how to solve it?i want this model for forecasting and i dont know that this problem is critical or not.i attach my dynare code.please help me.

Use

```auto
stoch_simul(irf=0, graph_format=(pdf), nograph) ;

```

to see that most variables in your model have `NaN` moments. It is highly unusual for real variables in such a model to feature a unit root. I can only give you the generic advice: check all your equations for mistakes.
