SaTScan (TM) seems to be a Java GUI on a whole bunch of scan
statistics devised by Kulldorff. Running RSiteSearch("kulldorff")
doesn't find any implementations of space-time scan statistics in R.
So I'm thinking not.
But it would be a heck of a great project to start. SaTScan (TM) is
closed source, but has a fairly permissive license (it allows
redistribution). I thought it would be able to produce pretty maps
like on its web page, but that appears to be misleading - one would
have to load the output data into a GIS (or R) for mapping.
Also, don't forget that SaTScan(TM) is trademarked to Kulldorff so
you have to say (TM) every time you mention it. All the methods are
published, so reimplementations of them should not be covered by
trademark, patent, copyright problems (oh, I'm not a lawyer...).
So basically, the answer is no, but if Kulldorff reads this, how
about opening the source?
