Repairing Tom Swift’s Electric Factor Analysis Machine
Proper use of exploratory factor analysis (EFA) requires the researcher to make a series of careful decisions. Despite attempts by Floyd and Widaman (1995), Fabrigar, Wegener, MacCallum, and Strahan (1999), and others to elucidate critical issues involved in these decisions, examples of questionable use of EFA are still common in the applied factor analysis literature. Poor decisions regarding ...
متن کاملDerivation of Theory by Means of Factor Analysis or Tom Swift and His Electric Factor Analysis Machine
Problems in the use of factor analysis for deriving theory are illustrated by means of an example in which the underlying factors are known. The actual underlying model is simple and it provides a perfect explanation of the data. While the factor analysis "explains" a large proportion of the total variance, it fails to identify the known factors in the model, The illustration is used to emphasi...

متن کاملReliability Analysis of a Self-Repairing Embryonic Machine
The embryonics project proposes a family of cellular architectures with reconfiguration properties inspired by the ontogenesis of multicellular organisms. This paper proposes reliability models for the MICTREE embryonic architecture. The models are used to analyse the reliability of MICTREE arrays with different combinations of spare cells. The methodology followed to attain the models can be u...
متن کاملMitochondrial biogenesis: The Tom and Tim machine
More than 98 % of the 1000 or so distinct mitochondrial proteins are encoded in the nucleus and synthesized as precursors in the cytosol. The preproteins are kept in a translocation-competent conformation by interactions with cytosolic chaperones, and are targeted to the preprotein translocase of the outer mitochondrial membrane (Tom) that includes receptors proteins and a general import pore. ...
