Pardosa fulvipes (Araneae, Lycosidae) new to Slovakia
No full textDuring the post-colloquium excursion of the 18th European Colloquium of Arachnology in Slovakia in July 1999, I had the opportunity to collect a small material of wolf spiders at the boundary of the Slovak Paradise National Park c. 20 km south of Poprad. Except for two common species [Pardosa palustris (UNNAEUS) and P. pullata (CLERCK)], numerous females of Pardosa fulvipes (COLLETT) were taken. An additional specimen of the latter was captured at Stara Lesna close to the High Tatras National Park. P. fulvipes was not included in the catalogue of spider species recorded from Slovakia (GAJDOS et al. 1999) though it may previously have been overlooked due to misidentification with some other species in the pullata group

Informative censoring in piecewise exponential survival models
No full textThere are often reasons to suppose that there is dependence between the time to event and time to censoring, or informative censoring, for survival data, particularly when considering medical data. This is because the decision to treat or not is often made according to prognosis, usually with the most ill patients being prioritised. Due to identifiability issues, sensitivity analyses are often used to assess whether non-informative censoring can lead to misleading results. In this paper, a sensitivity analysis method for piecewise exponential survival models is presented. This method assesses the sensitivity of the results of standard survival models to small amounts of dependence between the time to failure and time to censoring variables. It uses the same assumption about the dependence between the time to failure and time to censoring as previous sensitivity analyses for both standard parametric survival models and the Cox model. However, the method presented in this paper allows the use of more flexible models for the marginal distributions whilst remaining computationally simple. A simulation study is used to assess the accuracy of the sensitivity analysis method and identify the situations in which it is suitable to use this method. The study found that the sensitivity analysis performs well in many situations, but not when the data has a high proportion of censoring
