Morphology

noncentral = central (semi-transparent) = non + central

Morphologically transparent as non- + central, but the statistical sense is a technical usage (nonzero noncentrality parameter) that learners may not infer fully from the components.

Etymology

Noncentral starts with non- meaning 'not' and the rest, central, means 'in the center', like the common word center. In statistics, a noncentral distribution is simply one that is 'not in the center' (not at zero), so it shows a shift away from the center.
