Morphology

regressor = regress (semi-transparent) = regress + or

A standard agentive/nominal formation from 'regress', but the use as a statistical predictor/variable is technical and not transparently deducible from the common verb meaning.

Etymology

Regressor comes from old Latin parts re- 'back' and gress 'step', like in the word regression. So a regressor in statistics is a variable that 'looks back' to help explain or predict changes in another variable.
