Difficulties when estimate a DSGE model

Estimation ML/Bayesian estimation
1

Dear all,
I am estimating a economic DSGE model with DYNARE,and i meet problems as follow:
??? Error using ==> chol
Matrix must be positive definite.

  Error in ==> metropolis_hastings_initialization at 52
  d = chol(vv);

  Error in ==> random_walk_metropolis_hastings at 58
   ix2, ilogpo2, ModelName, MhDirectoryName, fblck, fline, npar, nblck, nruns,
  NewFile, MAX_nruns, d ] = ...

  Error in ==> dynare_estimation_1 at 871
            feval(options_.posterior_sampling_method,'DsgeLikelihood',options_.proposal_distribution,xparam1,invhess,bounds,gend,data,...
            
  Error in ==> dynare_estimation at 62
  dynare_estimation_1(var_list,varargin{:});

  Error in ==> monetary at 247
  dynare_estimation(var_list_);

   Error in ==> dynare at 132
  evalin('base',fname) ;
  Since i am a beginner of dynare,i don't know how to solve the problem.I need your help,thank you very much.

Use mode_compute=6 (search the forum using Google on the issue, there are countless posts). Moreover, check the timing for k, particularly in the production function and the law of motion.

@salarcon Please recheck your model. Your exogenous processes are most surely wrong. Why do you have

log(Px) = rho*Px((-1))+ e; log(Pm) = mrho*Pm((-1));
with log on the left and levels on the right side?
