A property of two random processes 
and 
which states that the random set
 |
can be disregarded, i.e. that the probability of the set 
is equal to zero. If 
and 
are stochastically indistinguishable, then 
for all 
, i.e. 
and 
are stochastically equivalent (cf. Stochastic equivalence). The opposite, generally speaking, is not true, but for processes that are continuous from the right (left), stochastic indistinguishability follows from stochastic equivalence.
