Since, at each step, the generation of a discrete random variable is needed, we can use any algorithm that simulates an arbitrary discrete distribution.
Let in general X and Y be discrete random variables taking values x = ([x.
n[Pi]] be the set of discrete random variables taking values [w.
Below are the computational formulas for a discrete random variable with pdf [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and for a continuous random variable with pdf f: R[right arrow]R, respectively:
The inverse transform method can be adjusted for discrete random variables as well, if we consider the generalized inverse of the cdf i.
For describing discrete random variables associated with experiments, an important notion is that of Bernoulli trials.
of Texas at Dallas) provides MATLAB computer codes along with detailed examples and exercises with direct connections to the front lines, moving efficiently from basic probability to discrete random variables and their distributions, continuous distributions, computer simulations and Monte Carlo methods, stochastic processes, queuing systems, basic statistics, statistical inference, and regression.

Among the topics are data description and treatment, probability distributions for discrete random variables, multiple random variables, fundamental statistical analysis, confidence intervals and sample size determination, and reliability analysis of components.
