A Lei de Lotka na bibliometria brasileira

Authors: Urbizagástegui Alvarado, Rubén;

A Lei de Lotka na bibliometria brasileira

Abstract

Usando os dados reportados em artigos publicados em revistas brasileiras e trabalhos apresentados em congressos nacionais, replicaram-se as aplicações da Lei de Lotka à literatura brasileira em 10 campos diferentes. Utilizou-se o modelo do poder inverso pelos métodos do mínimo quadrado e probabilidade máxima. Das 10 literaturas nacionais analisadas, somente a literatura de medicina, siderurgia, jaca e biblioteconomia ajustaram-se ao modelo do poder inverso generalizado pelo método dos mínimos quadrados. No entanto, só duas literaturas (veterinária e cartas do Arquivo Privado de Getúlio Vargas) não se ajustaram ao modelo quando se usou o método da máxima probabilidade. Para ambas literaturas, tentaram-se modelos diferentes. A literatura de veterinária ajustou-se à distribuição binomial negativa, e as cartas do Arquivo Privado de Getúlio Vargas ajustaram-se melhor à distribuição Gauss-Poisson Inversa Generalizada.
