Web10/3/11 1 MATH 3342 SECTION 4.2 Cumulative Distribution Functions and Expected Values The Cumulative Distribution Function (cdf) ! The cumulative distribution function F(x) for a continuous RV X is defined for every number x by: For each x, F(x) is the area under the density curve to the left of x. F(x)=P(X≤x)=f(y)dy −∞ WebIs PMF derivative of CDF? So, the answer to your question is, if a density or mass function exists, then it is a derivative of the CDF with respect to some measure. In that sense, they carry the the same information. BUT, PDFs and PMFs don’t have to exist. CDFs must exist.
