摘要：We explore the application of Weibull model in age distribution of citations in scientific articles references, when this age is censored at the right side. The Weibull model has been applied to twelve journals in the field of applied economy, where the basic source of information comes from ISI. The censored age is due to the fact that the citations of 10 or more years appear accumulated in the ISI database. After the model has been fitted, we have built a two-dimensional analysis combining the impact factor, that picks up the short term citations, with the percentile 90, that measures the durability or validity period of the scientific articles.
