Hello, I am interested in using Morans I for different time intervals to detect disease clusters. Ultimately I would like to use CUSUM - or similar monitoring statistic to monitor the results of Morans I - similar to the work by Rogerson (2005) Spatial Surveillance and Cummulative Sum Methods in Spatial and Syndromic Surveillance for Public Health. Thus far - thanks to the list I have Morans I running in a loop for each day (however I found that on some days no data is recorded, this caused an error to get around this error I inc...

...king with routine surveillance, but it also offers an infrastructure for developers of new detection algorithms. Implemented outbreak detection algorithms are: * Stroup et al. (1989) * Farrington et al. (1996) * A Bayesian predictive posterior approach * Time varying Poisson means as documented in Rogerson and Yamada (2004) * Approximate CUSUM method for time varying Poisson means by Rossi et al. (1999) * A generalized likelihood ratio detector for time varying Poisson and and negative binomial means Modelling routines: * A Poisson and negative binomial model for the analysis of multivariate i...

No, you do not necessarily need the XY coordinates. You can also use polygon (field, in your case) adjacency information. See Rogerson, Peter A. 2001. _Statistical methods for geography_. Thousand Oaks: Sage. You might also look at GeoDA, a free and soon-to-be open source spatial analysis package. For your application, it might be easier to use than R.

Hello, I''ve several problems with quota on our testcluster: When I set the quota for a person to a given value (e.g. the values which are provided in the operations manual), I''m able to write exact the amount which is set with setquota. But when I delete the files(file) I''m not able to use this space again. Here is what I''ve done in detail: lfs checkquota
