Bernoulli Process

A Bernoulli process is a finite or infinite sequence of independent random variables X1, X2, X3, ..., such that

  • For each i, the value of Xi is either 0 or 1;
  • For all values of i, the probability that Xi = 1 is the same number p.

In other words, a Bernoulli process is a sequence of independent identically distributed Bernoulli trials.

Independence of the trials implies that the process is memoryless. Given that the probability p is known, past outcomes provide no information about future outcomes. (If p is unknown, however, the past informs about the future indirectly, through inferences about p.)

If the process is infinite, then from any point the future trials constitute a Bernoulli process identical to the whole process, the fresh-start property.

Famous quotes containing the word process:

    Experiences in order to be educative must lead out into an expanding world of subject matter, a subject matter of facts or information and of ideas. This condition is satisfied only as the educator views teaching and learning as a continuous process of reconstruction of experience.
    John Dewey (1859–1952)
