From what I can see, the issue is parameters being updated in the steady state file. Identification in `4.7` seems unable to handle this. If I am not mistaken (@rattoma should know better), this is a regression as in the past, we resorted to simulation instead of theoretical derivatives which are now unavailable.

```

- Even more problematic, without any indication in the manual, using `morris=1` overwrites almost all other user-specified options:

See the attached file [test1.mod](/uploads/2c7fa958781bb4ea203ecb1d484c9c8d/test1.mod).

The treatment of unit roots seems unsatisfactory.
First, one needs to specify
`options_.diffuse_filter=1;`
because `options_` used in `dynare_estimation_init` does not inherit the `lik_init` from the `identification` command (used only in `options_ident`) and also does not accept `diffuse_filter`.
Second, some graphs are empty. My guess is because some unconditional moments are infinite.

There is an obvious bug in set_shocks_param.m. Sigma_e_ should be just Sigma_e. But there seems to be more. In stab_map_.m in
if pprior,
for j=1:nshock,
if opt_gsa.morris~=1,
lpmat0(:,j) = randperm(Nsam)'./(Nsam+1); %latin hypercube
end
if opt_gsa.prior_range
lpmat0(:,j)=lpmat0(:,j).*(bayestopt_.ub(j)-bayestopt_.lb(j))+bayestopt_.lb(j);
end
end
bayestopt_.ub and lb are accessed and they are Inf. lpmat0 then has a bunch of NaNs that should not be there. This seems to be due to ML estimation and should probably be filtered out.

Now, there is a forge package for octave

1. The problem is that after `identification_analysis` resets the number of autocorrelations, we have the line
`evalin('caller',['options_ident.ar=',int2str(nlags),';']);`
that is, only in the original caller, which is `dynare_identification.m`, is it reset. When the mod-file now reaches `simulated_moment_uncertainty.m` the variable accessed is `options` and not `options_ident` where `ar` is still at the old value.
I am not sure what is the best design choice to solve this issue. That is why I would leave it to you.
2. Now use
```
estimated_params;
//stderr eps_1, 0.01, 0, 1;
stderr eps_2, 0.01, 0, 1;
//stderr eps_3, 0.01, 0, 1;
root1, 0.95, -0.9999, 0.9999;
// root2, 0.55, -0.9999, 0.9999;
end;
```
instead and there will be a different crash due to nonconformable dimensions in `S=[S;zeros(size(JJ,2)-length(indJJ),1)];` in `identification_analysis`
1. I wonder why the standard deviation of eps_2 is not identifiable in the original mod-file, but the likelihood function shows curvature, although ML is used.

instead and there will be a different crash due to nonconformable dimensions in `S=[S;zeros(size(JJ,2)-length(indJJ),1)];` in `identification_analysis`
1. I wonder why the standard deviation of eps_2 is not identifiable in the original mod-file, but the likelihood function shows curvature, although ML is used.

- Check treatment of various options and trends in smoother used in `imcforecast.m`
- Check treatment of these issues in `identification`
- Adjust `convert_dyn_45_to_44` to reflect these changes
- Add trend estimate to output from `prior_posterior_statistics_core`

In older versions of Matlab, eig only has two output arguments and hence this causes an error. To calculate `W`, the left eigenvectors of cc, the documentation recommends `[W,junk] = eig(cc.'); W = conj(W)` separately.
