Tests of Randomness: Unidimensional and Multidimensional [PDF]
Environment and Planning A: Economy and Space, 1985 A variety of tests for randomness are reviewed based on simple product—moment statistics defined between two matrices, { a ij } and { b ij }. Typically, the first matrix, { a ij }, contains proximity data on the ...

Unidimensional Scale for Dementia
Dementia and Geriatric Cognitive Disorders, 2001A cognitive test comprising 27 subscales was administered to 262 demented patients and 92 normal subjects. Principal factor analysis followed by varimax and Harris-Kaiser rotation and Guttman’s scalogram analysis was performed. The analysis yielded three factors, i.e. ‘recent memory’, ‘immediate memory or attention’ and ‘remote memory’.

Unidimensionality of Alcohol Dependence Syndrome
Drug and Alcohol Dependence, 1992To evaluate the coherence of Alcohol Dependence Syndrome (ADS), as per DSM-III-R criteria, 72 and 223 subjects with alcohol dependence disorder from Hospital and Community settings, respectively, were interviewed. Nine DSM-III-R criteria assessing the dependence syndrome were factor-analysed.

Stochastic Dominance on Unidimensional Grids
Mathematics of Operations Research, 1995Special stochastic-dominance relations for probability distributions on a finite grid of evenly-spaced points are considered. The relations depend solely on iterated partial sums of grid-point probabilities and are very computer efficient. Their corresponding classes of utility functions for expected-utility comparisons consist of functions defined on

UNIDIMENSIONAL SIMILARITY REVISITED
Scandinavian Journal of Psychology, 1966It is argued that the use of direct scaling methods to derive the perceptual magnitudes in the similarity function is inadvisable on two grounds. (1) Attention may shift from one way of rating to another and thereby affect the perceptual magnitude so that what is rated may depend on the method of rating.

Systems Research and Behavioral Science, 2002
AbstractFrom carbon‐based organic molecules to body plans and thought, most living beings are built on linear structures that can be adequately described by unidimensional variables. Among known physical phenomena, electrical polarization is identified as a possible mechanism that assembles ordinary atoms into linear structures.

Is There a Unidimensional Alcohol Dependence Syndrome?
British Journal of Addiction, 1980SummaryThe elements of the provisional description of the Alcohol Dependence Syndrome were operationalised into a structured interview given to 109 men attending an alcoholism treatment unit. A single underlying dimension could not be demonstrated. The main dimension comprised Subjective Need, Withdrawal, and aspects of Salience.

On the unidimensional fuzzy equivalence relations
International Journal of Intelligent Systems, 1999The dimension of a fuzzy equivalence relation is the minimum number of fuzzy sets needed to generate it. A general theorem is proved that characterizes unidimensional fuzzy equivalence relations. The multidimensional case is also studied under some restrictive conditions (regular fuzzy equivalence relations).

Note on Guttman Unidimensional Scaling
Psychological Reports, 1966This paper reviews the concept of Guttman cumulative or unidimensional scaling and presents an added requirement that such scales must have a completely positive matrix of item intercorrelation. 1
