Note that there are some distributions that can be derived from the others (continuous as well as discrete).
For example student and chi-square distribution are derived from normal distribution and binomial distribution can be derived from Bernoulli distribution.
Of course, the term "derived" can be understood in two ways - directly derived (for example normal - student) or using some limit (binomial - poisson).
Is there any diagram depicting these kind of relation? If not, it is possible to draw it with at least the most known discrete and continuous distributions? I would prefer graph with nodes as distributions and directed edges that would mean that one distribution can be derived from another (limit cases should be also depicted).
