Discussion of "Spatial statistics, Marks, maps and shapes"

A. Stein from the Department of Earth Observation and Geoinformation Science, University of Twente, Enschede, The Netherlands discusses spatial statistics and its relationships with marks, maps and shapes. The first and foremost issue is the recent development of space-time procedures. It is a straightforward extension of spatial statistics domain, and it has currently received so much attention that its mentioning is important. Space-time point patterns have been addressed by Gabriel and Diggle in 2009. Another issue that is being debated in spatial statistics concerns integrated nested Laplace approximations (INLAs), a relatively new development that has found a place in spatial statistics.
