Thanks for all the informations
about Dawid's notation!
At the end of this mail you will find a brief summary.
I think I'll use the last one, a slightly modified version of
a suggested macro.
Regards,
Olivia
P.S.: Grazie ai vari italiani che hanno risposto, sembra che
Dawid sia molto popolare in Italia...
PP.SS.: ...yes, I'm writing my PhD. thesis (on causal modeling)!
