Talk:Predictable process

Need clarification of definition in lead

Currently the lead sentence says

In stochastic analysis, a part of the mathematical theory of probability, a predictable process is a stochastic process whose value is knowable at a prior time.

This needs to be clarified in language as non-technical as possible. How can a process whose value is knowable at a prior time be a stochastic process? Loraof (talk) 15:27, 5 June 2015 (UTC)

Hello fellow Wikipedians,

I have just added archive links to one external link on Predictable process. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

• Added archive https://web.archive.org/20120331074812/http://www.math.ku.dk/~jesper/teaching/b108/slides38.pdf to http://www.math.ku.dk/~jesper/teaching/b108/slides38.pdf

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

• December 17, 2018: Probably one should delete the above external link; first of all the file is no longer in its original place and has to be dig out through the Wayback Machine, moreover it seems on the first page there is an incorrect statement ("H(t) is a predictable process if and only if H(t) is {\mathcal F}_{t−} measurable").

Is it even true that every deterministic process is predictable?

Shouldn't it be left continuous or possess some weaker property? If it's not measurable, it wouldn't even be progressive, but predictability should imply progressiveness. 194.230.158.20 (talk) 02:58, 3 January 2023 (UTC)
