arctan not implemented?
this distribution seems hard to implement. the only path to it on the UDR is from cauchy. the transformation from cauchy is called a zero truncate, which is an algebraic manipulation of the PDF for cauchy. so, it cannot be implemented that way.
I have updated the list with comments.
Distributions without comments should be easily implementable at this point.
Distributions marked "Source" cannot be implemented at present unless otherwise stated.

Continuous
