Dear all,

Does anyone know what does “info=3” mean when running MH iteration? What is the cause of that problem (why it appears in some blocks of my iteration but not the others) and how can I avoid the problem?

Thanks…

Regards,

Wing

Nothing to worry about. It is a semicolon forgotten somewhere.

info is set to 3 when a set of parameter values deliver an infinity of stable solutions (the dynamics are indetermined). In Metropolis such a set of parameter values is always rejected

It is somewhere around line 240 of the file dr1.m, there is a line saying

info(1) = 3

you should add a semicolon at the end of that line

Thanks. It is now corrected on SVN
