The expected number of 0-1 strings of a limited length is a potentially useful index of the behavior of stochastic processes describing the occurrence of critical events (e.g., records, extremes, and exceedances). Such model sequences might be derived by a HoppePolya or a Polya-Eggenberger urnmodel interpreting the drawings of white balls as occurrences of critical events. Numerical results, co...
