SAS Genetics at Tufts

After surveying departmental chairs at the Tufts Medical School and Sackler School of Graduate Biomedical Sciences, UIT has purchased the licensing of the SAS Genetics module as an add-on to the SAS Educational Analytic Suite software bundle that Tufts renews every year. The SAS Genetics module is now available, at no additional cost to users, for installation with every SAS license that has been purchased under Tufts’ annual volume license renewal. The only restriction pertains to the SAS version in use. SAS has only released the Genetics module for SAS version 9.2 32-bit and SAS version 9.2 64-bit. Therefore, use of the new SAS Genetics module may require upgrading to one of these 2 versions of SAS. Please contact your local FSP(IT support person) if you need to purchase SAS or have SAS Genetics added to your current SAS installation.

If you only need access to a wide variety of easy to access graphics and some basic stats functionality you might like this product. Most everyone finds it very user friendly. SigmaPlot is available under Tufts’s network concurrent license. Along the sames lines, if you are looking for a free student version of a statistics package, try Systat’s MyStat. What a deal!

Bayesian Nonparametric Kriging

Statistical spatial analysis methods are evolving at a rapid rate as a result of increased active basic research and new journals promoting such methods in applied settings. One such journal is the Journal of Agricultural, Biological, and Environmental Statistics. An article by authors Woodard, Wolpert and O’Connel, Spatial Inference of Nitrate Concentrations in Groundwater, June 2010, illustrates nicely the application of nonparametric bayesian kriging via a spatial moving average model. This approach improves upon traditional kriging methods in many ways. The authors provide an S-Plus software package, spatialLrf, to implement the new algorithm.
