### Table 1: Predictor variables for the tick data. Classi cation trees A classi cation tree model for the presence or absence of Ixodes ricinus can be realized as the hierarchical subdivision of the space of predictor variables into regions which are labeled to identify areas of greater risk for ticks presence. Starting from the entire dataset, a subdivision is realized for each node of the tree. A classi cation label is attached to the node depending on the most numerous class in the node. Splits do not require the introduction of a metrics or an order for each factor, thus tree-based classi ers are appropriate for variables of di erent 4

"... In PAGE 9: ... according to a standard procedure at each site, with 15?min agging of 1 m2 white annel on single-day visits at each site. The 15?min ag- ging covered a linear transect of about 200 m, mainly along the edge of paths into woods, coppices and shrubby ecotones ( Table1 ); these habitat patterns are highly frequented by hikers. Ecological and environmental factors were recorded for each site, with the aim of identifying the main environmental patterns of the district which could be potentially suitable for supporting populations of I.... ..."

"... In PAGE 8: ... The maximal ray-recursion depth was set to 4. The results for tested scenes and methods are given in Table2 in means of the experimental measure lt; ; gt;. In order to decrease further the time complexity of ray{casting the concept of mailboxes [2] was used for testing of all acceleration methods.... In PAGE 8: ... The measurements were conducted on Pentium-MMX based PC, 166 MHz, 32 MBytes RAM, running under Linux operating system. Discussion The results in Table2 show that the subdivision tree built up using the surface area heuristics is always quicker than Kaplan apos;s BSP tree (constructed by splitting in the spatial median and with regular change of splitting planes orientation). This di erence can be very signi cant, when the objects are non{uniformly distributed in the scene (scene balls and tree).... ..."
