lack of fit

the degree to which the values predicted by a model—typically, one developed in regression analysis, structural equation modeling, or confirmatory factor analysis—diverge from the corresponding empirical values. A large, significant value from a goodness-of-fit test indicates a poorly fitting model.

consistent missing

in parapsychology experiments using Zener cards or similar targets, the phenomenon in which a participant’s “calls,” or guesses, are consistently wrong or significantly below chance expectations. Some people attribute such systematic failure to processing error or a conscious or nonconscious reluctance to confirm psychic ability. See also psi-missing.
