Statistical analysis for the Q‐factor of twin kHz QPOs [PDF]

open access: yesAstronomische Nachrichten, 2012
AbstractUsing the recently published data of twin kHz quasi‐period oscillations (QPOs) in neutron stars of low‐mass X‐ray binaries (LMXBs), we study the different profiles between bright Z sources and less luminous Atoll sources. The quality factors of upper kHz QPOs show a narrow distribution both for Z sources and Atoll sources, which concentrate at ...

Vintage factor analysis with Varimax performs statistical inference

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2023
Abstract In the 1930s, Psychologists began developing Multiple-Factor Analysis to decompose multivariate data into a small number of interpretable factors without any a priori knowledge about those factors. In this form of factor analysis, the Varimax factor rotation redraws the axes through the multi-dimensional factors to make them ...
