Censored quantile regression models are very useful for the analysis of censored data when standard linear models are felt to be appropriate. However, fitting censored quantile regression is hard numerically due to the fact that the objective function that has to be minimized is not convex nor concave in regressors. The performance of standard methods is(More)

Saline solution, 5% or 12% albumin were used as plasma substitutes. The treatment lead to rapid fall in urine porphyrin level and improved clinical picture. The treatment was(More)
Abstract. Let (Xn) be a strictly stationary sequence with a marginal distribution function F such that 1 − F (x) = x−αL(x), x > 0, where α > 0 and L(x) is a slowly varying function. We assume that only observations of (Xn) are available at certain points. Under assumption of weak dependency we proved the consistency of Hill’s estimator of the tail index α(More)
