The basic ingredient of a Monte Carlo simulation is the generation of random numbers (see, for example, Owen, 1962). Random numbers can, for example, begeneratedtoconsistofsingledigitshavingthediscreteuniformdistribution with k = 10. Using the digits 0 through 9, such random digits can be used to simulate the outcomes of Example 2.2. For each simulated interview we generate a random digit. If the value of the digit is 0 or 1, the outcome is had childhood measles; otherwise (digits 2 through 9) the outcome is did not. The outcome had then occurs with a probability of 0.2. The result of the experiment involving a single couple is then simulated by using a pair of such integers, one for each individual.
