I am completely new to Dynare so I am having a few troubles using it. I am getting the following errors: You did not declare endogenous variables after the estimation command.

For starters ignore the first warnings. They are not errors. Apparently, there is a problem with some beta priors like mean and standard deviation are inconsistent. The true problem is your combination of the varobs command and your data-file. However, without the mod- and the data-file it is impossible to tell what is going on. ---

Thank you.now the error that I am getting says: POSTERIOR KERNEL OPTIMIZATION PROBLEM! (minus) the hessian matrix at the “mode” is not positive definite! =\> posterior variance of the estimated parameters are not positive. You should try to change the initial values of the parameters using the estimated\_params\_init block, or use another optimization routine.

Please search the forum, this is one of the most common threads. A short answer is: Try using mode\_compute=6 in the estimation command.
