We generalize the test proposed by Kojadinovic, Segers and Yan which is used for testing whether the data belongs to the family of extreme value copulas. We prove that the generalized test can be applied whatever the alternative hypothesis. [...]

10 p, 535.4 KB Empirical comparison between the Nelson-Aalen Estimator and the Naive Local Constant Estimator / Pérez-Marín, Ana M. (Universitat de Barcelona)
The Nelson-Aalen estimator is widely used in biostatistics as a non-parametric estimator of the cumulative hazard function based on a right censored sample. A number of alternative estimators can be mentioned, namely, the naive local constant estimator (Guillén, Nielsen and Pérez-Marín, 2007) which provides improved bias versus variance properties compared to the traditional Nelson-Aalen estimator.

31 p, 240.4 KB Testing extreme value copulas to estimate the quantile / Bahraou, Zuhair ; Bolancé Losilla, Catalina ; Pérez Marín, Ana María ; Xarxa de Referència en Economia Aplicada (XREAP)
Testing weather or not data belongs could been generated by a family of extreme value copulas is difficult. We generalize a test and we prove that it can be applied whatever the alternative hypothesis. [...]
