The Use of Factor Analysis in the Statistical Analysis of Multiple Time Series

Psychometrika, 1963
Factor analysis has been proposed and used as a method of statistical analysis of several measurements made on one individual repeatedly over time. This paper discusses some difficulties in applying factor analysis to multiple time series and attempts to indicate to what extent such methods can accomplish the goals of time series analysis.

Statistical Aspects of a Three-Mode Factor Analysis Model

Psychometrika, 1978
A special case of Bloxom's version of Tucker's three-mode model is developed statistically. A distinction is made between modes in terms of whether they are fixed or random. Parameter matrices are associated with the fixed modes, while no parameters are associated with the mode representing random observation vectors.

A statistical analysis of factors predisposing patients to heparin resistance

Perfusion, 2006
Heparin resistance (HR) is occasionally encountered in cardiac surgery. The objective of this study is to identify possible factors predisposing patients to heparin resistance. Four hundred patients scheduled for elective cardiac surgery requiring the use of cardiopulmonary bypass (CPB) were enrolled in this study.

A statistical analysis of factors related to symptomatic cerebral vasospasm

Acta Neurochirurgica, 1994
A retrospective review of patients presenting to our institution with aneurysmal subarachnoid hemorrhage between 1980-1990 was accomplished. Eleven variables were examined as to their relationship to clinical vasospasm: age, sex, clinical grade, amount of subarachnoid blood on CT, aneurysm location, incidence of vasospasm, incidence of complications ...

Prognostic significance of the age factor in the thyroid cancer: Statistical analysis

Journal of Surgical Oncology, 2004
AbstractBackground and ObjectivesTo determine whether thyroid carcinoma in elderly patients presents any peculiar characteristics, whether the greater biological aggressiveness of the neoplasm modifies the surgical treatment selected, and whether age greater than 70 years represents an independent prognostic factor.MethodsRetrospective analysis of case

Robustness of Statistical Inference in Factor Analysis and Related Models

Biometrika, 1987
In this paper the author considers a class of latent variable models which includes the unrestricted factor analysis model. In this class of models it is shown that normal theory tests of fit and sequential difference tests retain all their asymptotic properties when common factors are fixed or have nonnormal distributions. The minimum discrepancy test

The Statistical Analysis of Prognostic Factors for Brain Tumors

1996
The study population consisted of cases diagnosed as astrocytoma (AS), malignant astrocytoma (MA), and glioblastoma multiforme (GM) in the supratentorial region and listed by the Brain Tumor Registry of Japan from 1978 to 1987. Prognostic factors (PFs) for survival were analyzed by the Kaplan-Meier (KM) method, Cox proportional hazards (Cox) model ...
