Consider a collection of variables
{x1, x2, x3, ...}
that are distributed according to the function
Px(x),
then the probability of finding a value that lies between
x and
x+dx is
Px(x)dx.
If y is some function of
x then we can write:
where Py(y) is the probability density that describes the collection {y1, y2, y3, ...}.
Px(x) = C (i.e. Uniform) and so Py(y) = C |dx/dy| |
