Aggregate Stability in Repeated Restricted Geometric Experiments with Heterogeneous Cutoffs

Consider m independent Bernoulli sequences with a common success probability 0 < p < 1, each stopped at the first success or at a prescribed cutoff. We allow the cutoffs to form an arbitrary deterministic sequence, with finite and unrestricted cutoffs permitted. We prove that the...

Homogeneous Cutoff Monotonicity and a Sharp 2/3 Coordinate-Wise Threshold in Repeated Restricted Geometric Experiments

We consider m independent sequences of Bernoulli trials with success probability p, each terminated at its first success or after n trials, whichever occurs first. We study how the expected proportion of successes among all trials performed across the m components changes as the...

The Aggregate Success Rate in Repeated Restricted Geometric Experiments: Expectation, Monotonicity, and Convergence

We consider m independent sequences of Bernoulli trials with success probability p, each terminated at its first success or after n trials, whichever occurs first. Let Xm,n,p denote the proportion of successes among all trials performed across the m components. We derive a unifie...
