    Stick-breaking process vs. flat dirichlet?

    This might be a stupid question, but however...

    I have randomly picked three variables (between 0-1) from an equal distribution. I let them form the "breaking points" on an imagined stick of the length 1.

    Do the four "pieces" obtained (which together sum up to 1, ofcourse) represent a set of variables from a flat dirichlet distribution?

    Thank you in advance for any help!!!

    With some help, I have confirmed this: In the above case, the four variables have a uniform Dirichlet distribution (=flat Dir), for a standard "3-simplex".
