Conditions for Factor (in)Determinacy in Factor Analysis [PDF]
Psychometrika, 1998 The subject of factor indeterminacy has a vast history in factor analysis (Guttman, 1955; Lederman, 1938; Wilson, 1928). It has lead to strong differences in opinion (Steiger, 1979). The current paper gives necessary and sufficient conditions for observability of factors in terms of the parameter matrices and a finite number of variables.

Conditional Risk Factors for Atherosclerosis [PDF]
Mayo Clinic Proceedings, 2005 Although most patients who experience a coronary heart disease (CHD) event have one or more of the conventional risk factors for atherosclerosis, so do many people who have not yet experienced such an event. Therefore, predictive models based on conventional risk factors have a lower than desired accuracy, providing a stimulus to search for new tools ...

Testing Conditional Factor Models [PDF]
SSRN Electronic Journal, 2009 We develop a new methodology for estimating time-varying factor loadings and conditional alphas based on nonparametric techniques. We test whether long-run alphas, or averages of conditional alphas over the sample, are equal to zero and derive test statistics for the constancy of factor loadings. The tests can be performed for a single asset or jointly

Conditions for the existence of maximal factorizations
Fuzzy Sets and Systems, 2020 Extending classical algorithms for ordinary weighted or string-to-string automata to automata with underlying more general algebraic structures is of significant practical and theoretical interest. However, the generalization of classical algorithms sets certain assumptions on the underlying structure.

On conditional permutability and factorized groups [PDF]
Annali di Matematica Pura ed Applicata (1923 -), 2013 Two subgroups and of a group are said to be totally completely conditionally permutable (tcc-permutable) if permutes with for some , for all and all . In this paper, we study finite products of tcc-permutable subgroups, focussing mainly on structural properties of such products. As an application, new achievements in the context of formation theory are

Morphological observations, length-weight relationships, and condition factors of the Whipfin fish, Gerres filamentosus (Cuvier, 1829) in the Hurghada Red Sea, Egypt. [PDF]
Journal of Bioscience and Applied Research, 2016 During the period from January 2010 to December 2010, the biometric studies of 669 (both sexes- 12:39 centimeters) the whipfin, silver biddy, Gerres filamentosus (Cuvier,1829) have been described to clarify the identity of the fish population in the ...

Brycon hilarii produced in hapas: effects in allometric growth [PDF]
Brazilian Journal of BiologyBiometric evaluations are essential to determine the growth characteristics related to the weight and length of fish. This study aimed to determine the growth patterns of juvenile piraputangas (Brycon hilarii) produced in hapas within an excavated pond ...

Interpretational factors in conditional reasoning [PDF]
Memory & Cognition, 1994 Two experiments examined the role of necessity and sufficiency relationships in conditional reasoning. The results indicated that perceived necessity and sufficiency predicted variability in reasoning performance for four pragmatic relations (permission, obligation, causation, and definition), for both determinant and indeterminant syntactic forms, and
