▪PX=b=FXb−FXb−.▪PX>x=1−FXx. Figure 4.7 shows cdf examples for continuous and discrete random variables. FX(x) is a continuous function for a continuous random variable. It is important to note that if the cdf is continuous at a point c, then PX=c=0. This is an ...
The algorithm for the RNG should be programmable in a high-level computer language like FORTRAN or C. This requirement ensures the RNG does not depend on a particular architectural feature of one type of computer system. Efficiency: This attribute refers to the speed with which an RN is genera...
