Can anyone help explain what is a 2-point distribution?
the data can only take 2 values?
and what is the joint pdf of the distribution?
I would assume that it is a probability distribution with all the probability mass at two points.
For example p(x)=0 for all x in R, except at x=0, where p(0)=1/2 and x=1, where p(1)=1/2.
