Resumen:
We present here the re-analysis of fast variability results for a sample of active galactic nuclei (AGNs) that were presented in Zibecchi et al. (2012, BAAA, 54). In this work we study the application of the F statistics, which is based on the ratio of variances. The motivation to make this re-analysis is because some authors have begun to use this statistics during the last years, but still there is no complete analysis of the differences between the different tests and their respective advantages or disadvantages. We found that, in some cases, the state of variability depends on the test used. We thus made a comparison of the results obtained by applying different statistics in order to decide which of them is the most efficient and reliable.
