Hi,  
I am trying to loop over parameter a value. I tried following this post, but it does not seem to work: [Loop over parameters](https://forum.dynare.org/t/loop-over-parameters/3335/1)

I am trying to loop over ‘h’ paramtere in NK\_Baseline.mod as an example, but I get the error message:

```auto

```

Here is the outside loop I am calling:

[code]params = 0:0.05:0.95;  
for lpPar=1:length(params)

```
    set_param_value('h',params(lpPar));
    dynare NK_baseline noclearall;  

```

[STUFF]

end[/code]

Somehow it does not seem to recognize the value assignment I do when calling `set_param_value` (although I am able to call this function just fine).

Thanks.

That’s because the call to

`dynare NK_baseline 
`  
will overwrite the initial statement setting h. That’s why the post you refer to only calls resol/stoch\_simul within the loop, but not full Dynare.

Is there anyway to work around that? Should I call the loop from inside dynare mod file?  
Thanks.

I am working on posting some sample files, but if I just need to simulate new data with new parameter values, all I need is to follow the post I referred to? I am asking this because I wondering if just calling stoch\_simul again with the new paramter would calculate the steady states again, since the changing parameters could potentiall y affect steady state.  
Thanks.

Yes, stoch\_simul will recalculate the steady state (as does resol.m)

Great thanks. Managed to work around it.
