Default of mh_conf_sig generates NAs

Good morning to all,

I am estimating a simple Solow model using bayesian methods. When I set mh_conf_sig>= 0.9 both HPDinf and HPDsup become NAs; also, how can the small gaps in the graphs related to the estimation function output (e.g., bayesian_irf) be eliminated, I am using Octave. Here is the code of my model:

% warning('off')
% addpath /opt/homebrew/opt/dynare/lib/dynare/matlab
% pkg load io
% dynare Solow_mod.mod

% Simple Solow Model

var Y K Z C I;
varexo e;

parameters alpha delta s rho;  % Declare parameters

alpha = 0.35;  % Parameter values
delta = 0.025;
s = 0.1;
rho = 0.75;   % Autoregressive parameter for the technology shock

% Model equations
model(linear);
  C=Y;
  I=Y;
  Y=Z+K(-1)*alpha;
  K= (1 - delta)*K(-1) + delta*I;
  Z = rho*Z(-1)+e;
end;


initval;
Y=0;
K=0;
Z=0;
I=0;
C=0;
end;

shocks;
  var e; stderr 1;
end;

steady;
check;

stoch_simul;

results1=oo_.irfs;

estimated_params;
alpha, beta_pdf, 0.35, 0.02;
delta, beta_pdf, 0.025, 0.02;
end;

varobs C;

estimation(datafile=rbc_data,mh_replic=200,mh_conf_sig=0.9,bayesian_irf) Y K Z C I;

oo_.PosteriorIRF.dsge

I also upload a figure with the gaps and the database used for estimation. I would appreciate any indication.

Thank you very much,

is not sufficient to generate any meaningful results.

Thank you very much for your reply.
