Talk:Stopping time

Clockstopping a watch that stops time.

Wald's equation
somebody should put a reference to Wald's equation into the article. A link under "See also" would be a start, but maybe we could mention it in the text itself? &mdash;MoA)gnome (talk) 22:29, 22 March 2008 (UTC)

Change of subject?
Te article defines stopping time, and then gives examples of stopping *rules*. This is a sudden change of nomenclature.

Frankly, the term "stopping rule" is much more intuitive than the term "stopping time", due to the various synonymous meanings of the words involved ("stopping time" first calls to mind something out of some SF story or other).

A better introductory paragraph might use both the term (stopping time) and the intuitive term (stopping rule) in order to give the reader an immediate intuitive grasp on the concept, something such as:

A "stopping time" is a time ... defined by a stopping rule; for example the rule "stop after playing 500 games" can be used to define a stopping time. —Preceding unsigned comment added by 207.22.18.83 (talk) 13:55, 5 May 2010 (UTC)

Domain
A stopping time is defined as a random variables mapping into the nonnegative integers and infinity. What is the domain of this random variable? 203.167.251.186 (talk) 02:41, 24 May 2010 (UTC)
 * The domain of the stopping time is the probability space &Omega; on which the process of interest is defined. AxelBoldt (talk) 00:46, 19 December 2013 (UTC)

Examples
Playing until he doubles his money is a stopping rule unless you define stopping time with the restriction that t is almost surely finite. No? Angry bee (talk) 07:48, 7 July 2011 (UTC)
 * Yes, that is correct. AxelBoldt (talk) 00:46, 19 December 2013 (UTC)

The opening sentence is overly complicated and both it and the definition are both very hard to comprehend for a non-specialist
The language on this page boarders on the impenetrable. The opening sentence currently is:

"In probability theory, in particular in the study of stochastic processes, a stopping time (also Markov time) is a specific type of “random time”: a random variable whose value is interpreted as the time at which a given stochastic process exhibits a certain behavior of interest."

After a few reads, I believe I understand what it is saying. I wonder if it is possible to make this even a little more accessible in terms of language, or intuitive in terms of description. Pigkeeper (talk) 08:18, 5 April 2017 (UTC)
