nonlinear transformation

a transformation of a data set that uses a function to change the linear relationship between variables. For example, a normalizing transformation creates a new set of scores that approximate a normal distribution from the original nonnormal data set, and a logarithmic transformation may be used to convert raw data into a form that more closely matches the assumptions required in particular statistical analyses. Compare linear transformation.

antilibidinal ego

in the object relations theory of British psychoanalyst W. Ronald D. Fairbairn (1889–1964), the portion of the ego structure that is similar to Sigmund Freud’s superego. The antilibidinal ego constitutes a nonpleasure-gratifying, self-deprecatory, or even hostile self-image; it is posited to develop out of the unitary ego present at birth when the infantile libidinal ego (similar to the id) experiences deprivation at the hands of the parent and the infant suppresses his or her frustrated needs. Also called internal saboteur. See Fairbairnian theory.
