Purpose. measure of implicit attitude. The Implicit Relational Assessment Procedure (IRAP) is a computer-based psychological measure. It was heavily influenced by the implicit-association test, [1] and is one of several tasks referred to as indirect measures of implicit attitudes. [2] [3] The IRAP is one of relatively few indirect measures that ...
Ophthalmology. In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia. Even when the double vision images ...
It has to be noted, though, that the iterative Cochrane–Orcutt procedure might converge to a local but not global minimum of the residual sum of squares. This problem disappears when using the Prais–Winsten transformation instead, which keeps the initial observation. See also. Hildreth–Lu estimation; Newey–West estimator
Optical coating. An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which ...
White test is a statistical test that establishes whether the variance of the errors in a regression model is constant: that is for homoskedasticity . This test, and an estimator for heteroscedasticity-consistent standard errors, were proposed by Halbert White in 1980. [1] These methods have become widely used, making this paper one of the most ...
Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve ), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [1] The inability of an eye to turn outward, results in a convergent strabismus or esotropia of which the ...
Newman–Keuls method. The Newman–Keuls or Student–Newman–Keuls (SNK) method is a stepwise multiple comparisons procedure used to identify sample means that are significantly different from each other. [1] It was named after Student (1927), [2] D. Newman, [3] and M. Keuls. [4]
Ganzfeld experiment. A ganzfeld experiment (from the German words for "entire" and "field") is an assessment used by parapsychologists that they contend can test for extrasensory perception (ESP) or telepathy. In these experiments, a "sender" attempts to mentally transmit an image to a "receiver" who is in a state of sensory deprivation.
