Hidden variables may refer to:
- Hidden variable theories, in physics, the proposition that statistical models of physical systems (such as Quantum Mechanics) are inherently incomplete, and that the apparent randomness of a system depends not on collapsing wave functions, but rather due to unseen or unmeasurable (and thus "hidden") variables. In sharp contrast to the generally accepted Copenhagen Interpretation.
- Latent variables, in statistics, variables that are inferred from other observed variables
- Hidden transformation, in computer science, a way to transform a generic constraint satisfaction problem into a binary one by introducing new hidden variables
- Confounding or hidden variables in general. That is, a variable that actually creates the illusion of a causal relation (e.g. firemen often appear after smoke, not because smoke causes firemen, but because fire causes both smoke and firemen)
Famous quotes containing the words hidden and/or variable:
“Our courage breaks like an old tree in a black wind and dies,
But we have hidden in our hearts the flame out of the eyes
Of Cathleen, the daughter of Houlihan.”
—William Butler Yeats (18651939)
“There is not so variable a thing in nature as a ladys head-dress.”
—Joseph Addison (16721719)
