RESTREPO ARANGO, Cristina  and  URBIZAGASTEGUI ALVARADO, Rubén. Publications on the Pendulum: a comparative analysis. Investig. bibl [online]. 2012, vol.26, n.58, pp.153-173. ISSN 2448-8321.

This study examines the production of the literature on the pendulum published from 1629 to 1885. The findings of Moreno-Cabo & Solaz-Portolés (2008) are replicated. The data are analyzed through the following statistical methods: inverse square, generalized inverse power, and compound Poisson and Poisson log-normal by maximum likelihood models. The results show that the Poisson lognormal and generalized inverse power are those that estimate the observed authors most consistently. The statistical test Kolgomorov-Smirnov confirms the fit of the generalized inverse power, Poisson lognormal, and compound Poisson, while rejecting the inverse square model.
