Random Variables PDFs and CDFs. $\begingroup$ @styfle - because that's what a PDF is, whenever the CDF is continuous and differentiable. You can see this by looking at how you have defined your CDF. Differentiating an integral just gives you the integrand when the upper limit is the subject of the differentiation. $\endgroup$ вЂ“ probabilityislogic May 1 '11 at 1:00, We can comput the PDF and CDF values for failure time \(T\) = 1000, using the example Weibull distribution with \(\gamma\) = 1.5 and \(\alpha\) = 5000. The PDF value is 0.000123 and the CDF value is 0.08556. Functions for computing Weibull PDF values, CDF values, and for producing probability plots, are found in both Dataplot code and R code..
