Dear all, I regret to inform you that the gretl package "pmbb" for doing Moving Blocks Bootstrap (MBB) for linear panels has been removed from the package server. This is due to a potential bug in the package. We can't say when we find time to work at it to fix the bug. In the meantime, if you would like access to its source code, please visit https://github.com/atecon/pmbb . We would be grateful if anyone could assist us in detecting any errors present in its source code so we can return this package back into circulation quickly and safely! Thank you very much for your understanding and support. Best, Artur
