Bernoulli process, along with the associated random variables defined in Section 2.6: the number of additional trials needed for each additional outcome of a one (the L’s), the total number of trials needed for a given number of ones (the S ’s), and the cumulative number of ones for a given number of trials (the C ’s). Note that the index in the sketch is k , which indexes the trials, beginning with trial one. Figure 3.7(b) shows the corresponding time-scaled Bernoulli process for h = 0.1. The seventh trial is the first trial...
