is my dynare 4.3.3 version stable

Postby adeleke omolade » Tue Oct 01, 2013 6:13 pm

Am confused with the version of the dynare am using. to verify i tried to work with the prior steady state values of a friend who used another version of dynare. i used those value as inital values yet i could not get the staedy state. This makes me to question the statblity of my version. Please can any body also try it and tell me what is wrong the file is attached all the inital values are the prior steady state results obtained by another person with the same model.

But you did not provide any initial values for qm, qs, and M. They are initialized to 0 and lead to the error.

After adding the variable initial variables i have the following error. Note that all these values are the prior steady state values got by a friend using another version of dynare. Why am i not geting the same result with my dynare 4.3.3?

How about initializing all variables exactly the way he did? c, phi, and s are still not initialized.

Thank you after supplying everything i notice an improvemeny but yet the steady state has not come. this is what i got
what has happened and where is the problem because these are the values he used.

What exactly did you do? Did you use the exact steady state values from a different version of Dynare with the same mod-file and it does not run anymore? Or did you just use the same initial values for mode finding? Or are you using a different mod-file?

Yes what i did was that i used the prior steady state values from another version of dynare with the same mod.file and it does not run anymore with my own version.I used same mod. file. because i guess it should run easily with the steady state values provided as the initial values. Just doing it to see if my 4.3.3 version is stable or unstable.

What do you mean with stable? 4.3.3 is officially a "stable release" because it has a version number. Nevertheless, there have been documented bugs in it: http://www.dynare.org/DynareWiki/KnownBugs
But none of them affects steady state computations. A steady state of a mod-file must be a steady state in any version of Dynare! If it is not, you must be doing something wrong.
