Drawing random number from TH2

[NgJunKai]

Hi, experts,
I know that we can draw r.v from Th1 (using inverse sampling)
is there any equivalent for th2 ?
FYI my th2 distribution is having some dependence structure.

Cheers,

[NgJunKai]

yes.i also read the code.

what is the method employed in the code to draw r.v ?

You would like to know which algorithm used TH2::GetRandom2 ?
If that’s the case, @moneta should know.

[NgJunKai]

actually i would like to know what algorithm has implemented in GetRandom1/2/3
