Extinction or Explosion in a Galton-Watson Branching Process: Testing or Prediction?

چکیده

In a frequently cited paper, Becker (1974) asked whether data from a “mortal” (= terminated) smallpox outbreak better fit a subcritical or semicritical Galton-Watson branching process. We revisit this question using standard hypothesis-testing methods and reach a somewhat di↵erent conclusion than he did. For a non-terminated process, the related problem of predicting extinction or explosion also can be formulated in a testing framework to which standard Neyman-Pearson theory applies. ⇤[email protected].

Asymptotics of iterated branching processes

We study iterated Galton-Watson processes, introduced by Gawel and Kimmel as models of the number of repeats of DNA triplets during some genetic disorders. When the process (Xn)n involves some thinning, the extinction Xn → 0 and the explosion Xn → ∞ can have positive probability simultaneously. When the underlying (simple) Galton-Watson process is nondecreasing with mean m, conditional on the e...

On the scaling limits of Galton Watson processes in varying environment

Renormalized sequences of Galton Watson processes converge to Continuous State Branching Processes (CSBP), characterized by a Lévy triplet of two numbers and a measure. This paper investigates the case of Galton Watson processes in varying environment and provides an explicit su cient condition for nite-dimensional convergence in terms of convergence of a characteristic triplet of measures. We ...

Branching Processes: Their Role in Epidemiology

Branching processes are stochastic individual-based processes leading consequently to a bottom-up approach. In addition, since the state variables are random integer variables (representing population sizes), the extinction occurs at random finite time on the extinction set, thus leading to fine and realistic predictions. Starting from the simplest and well-known single-type Bienaymé-Galton-Wat...

Bounds on the Extinction Time Distribution of a Branching Process

The class of fractional linear generating functions, one of the few known classes of probability generating functions whose iterates can be explicitly stated, is examined. The method of bounding a probability generating function g (satisfying g"(1)< oo) by two fractional linear generating functions is used to derive bounds for the extinction time distribution of the Galton-Watson branching proc...

Branching Processes

The study of branching processes began in the 1840s with Irénée-Jules Bienaymé, a probabilist and statistician, and was advanced in the 1870s with the work of Reverend Henry William Watson, a clergyman and mathematician, and Francis Galton, a biometrician. In 1873, Galton sent a problem to the Educational Times regarding the survival of family names. When he did not receive a satisfactory answe...
