NOMINATION AS THE PRINCIPAL AXIS OF PUSHKIN’S THOUGHT

The Principal Axis of the Virgo Cluster

Using accurate distances to individual Virgo cluster galaxies obtained by the method of Surface Brightness Fluctuations, we show that Virgo’s brightest ellipticals have a remarkably collinear arrangement in three dimensions. This axis, which is inclined by ∼ 10 − 15◦ from the line of sight, can be traced to even larger scales where it appears to join a filamentary bridge of galaxies connecting ...

Principal Components Versus Principal Axis Factoring

Note that SPSS does not provide statistical significance tests for any of the estimated parameters (such as loadings), nor does it provide confidence intervals. Judgments about the adequacy of a oneor two-component model are not made based on statistical significance tests, but by making arbitrary judgments whether the model that is limited to just one or two components does an adequate job of ...

Principal Axis Analysis

Principal axis analysis rotates principal components to optimally detect cluster structure, rotation being based on a second spectral decomposition identifying preferred axes in the sphered data. As such, it complements principal component analysis as an extremely fast, general, projection pursuit method, particularly well-suited to detecting mixtures of elliptical distributions. Examples show ...

Angle between principal axis triples

S U M M A R Y The principal axis angle ξ 0, or Kagan angle, is a measure of the difference between the orientations of two seismic moment tensors. It is the smallest angle needed to rotate the principal axes of one moment tensor to the corresponding principal axes of the other. This paper is a conceptual review of the main features of ξ 0. We give a concise formula for calculating ξ 0, but our ...
