How to evaluate an ordered conditional PDF ?

  1. Nov 29, 2013 #1
    Hello,

    i would like to evaluate the following PDF:

    Let x1 ≥ x2 ≥ ... ≥ xL. What is the PDF of xi (where 1 ≤ i < L), given that xL ≥ T (where T is a predetermined fixed value) ??

    Any help would be useful.

    Thank you in advance

    You haven't told us what the unconditioned distribution is.

    Let' say that the unordered RVs are nonnegative and are from an i.i.d. chi-squared PDF with 2n degrees of freedom. But i m really looking for a generic expressions regardless of the distribution.
