Factor Analyses of the Family Assessment Device
Family Process, 1999The Family Assessment Device (FAD) operationalizes the McMaster Model of Family Functioning, which has been used in numerous studies, translated into seven languages, and is regarded as one of the most researched family assessment tools available. However, exploratory and confirmatory factor analyses using the 7‐by‐7 matrix of subscale correlations ...

Factor analysed hidden Markov models
IEEE International Conference on Acoustics Speech and Signal Processing, 2002This paper presents a general form of acoustic model for speech recognition. The model is based on an extension to factor analysis where the low dimensional subspace is modelled with a mixture of Gaussians hidden Markov model (HMM) and the observation noise by a Gaussian mixture model.

Factor Analyses of The DIB-R in Adolescents
Journal of Personality Disorders, 2002The goal of this study was to examine the factor structure of the Revised Diagnostic Interview for Borderlines (DIB-R; Zanarini, Gunderson, Franckenburg, & Chauncey, 1989) in a nonpatient sample of 118 adolescents. A principal components factor analysis with a Varimax rotation extracted three factors.

Componentwise perturbation analyses for the QR factorization
Numerische Mathematik, 2001Consider the QR factorization of a matrix \(A=QR\) and suppose that the factorization of the perturbed matrix is \(A+\Delta A=(Q+\Delta Q)(R+\Delta R)\). The perturbation analysis bounds \(\Delta Q\) and \(\Delta R\) in terms of \(\Delta A\). By using better, i.e., more elementwise individualized bounds for \(\Delta A\), and more accurate estimates for

Refined Error Analyses of Cholesky Factorization
SIAM Journal on Numerical Analysis, 1983This paper concentrates on the practical Cholesky process for solving positive definite symmetric systems of linear equations in standard floating-point arithmetic. Two self-contained round-off analyses are presented, which lead to novel a posteriors error bounds (of practical use) and to refined a priori results (of more theoretical significance ...

Factor Analyses of Format Frequencies
The Journal of the Acoustical Society of America, 1971The exact relationship between the phonetic quality of a vowel and its formant frequencies has never been stated, because it has not been possible to account for the variations due to the personal quality of a speaker. We have analyzed the fundamental and first three formant frequencies of the eight primary cardinal vowels as spoken by 11 phoneticians ...

SYNTHESIS OF FACTOR ANALYSES: III Interbattery methods of synthesis of factor analyses
Scandinavian Journal of Psychology, 1962Werdelin, I. Synthesis of factor analyses. III. Interbattery methods of synthesis of factor analyses. Scand. J. Psyehol., 1962, 3, 196–204.—Methods of performing several factor analyses on a common sample, so that we arrive at invariant structures, are discussed.

Parameter accuracy in meta‐analyses of factor structures
Research Synthesis Methods, 2016Two new methods for the meta‐analysis of factor loadings are introduced and evaluated by Monte Carlo simulations. The direct method pools each factor loading individually, whereas the indirect method synthesizes correlation matrices reproduced from factor loadings.
