* A third convention will be explained below. The third convention generalizes the second one, rather than actually conflicting with it. It allows ''r'' to be a non-integer.
 
The probability distributions called "negative binomial" according to the second and third conventions are [[infinite divisibility|infinitely divisible]]. The ones called "negative binomial" according to the first convenetion have the virtue that everyone's intuitive guess about their [[expectednilai valueekspektasi]] is correct; for example, if you repeatedly throw an ordinary six-sided die until you get a "1", on average it takes six trials, if you keep trying until you get two "1"s, it takes 12 trials on average, and so on.
