Import scipy.stats in a macro
From Apache OpenOffice Wiki
This script was published by hanya at the OpenOffice Basic, Python, BeanShell, JavaScript.
This script imports scipy.stats to perform calculations into a Writer document.
It was getting a deadlock during the calculation of iexp in numpy.core.machar.MachAr class.
