This Wikipedia page at least tries to explain the name as the stochastic interpretation of QM

> https://en.wikipedia.org/wiki/Stochastic_quantum_mechanics
> "Perhaps the most widely known theory where quantum mechanics is assumed to describe an inherently stochastic process was put forward by Edward Nelson [[6]](https://www.worldcat.org/title/dynamical-theories-of-brownian-motion-part-1/oclc/25799122) and is called stochastic mechanics. This was also developed by Davidson, Guerra, Ruggiero and others."

Nelson developed his "dynamical theory of Brownian motion" in 1966.
