Learn about the new COPULA procedure for using copulas to fit multivariate distributions from a given sample data set, the new SSM procedure for state space modeling when the data might be irregularly spaced, and the newly production SEVERITY procedure for fitting probability distributions for the severity or magnitude of random events.

Both the UNIVARIATE and the KDE procedures are illustrated.  And for fun, take a look at this post, which is about Buffron's needle experiment to estimate pi.</p> Tue, 28 Feb 2012 13:00:00 GMT http://blogs.sas.com/content/iml/?utm_medium=RSS&utm_source=Support_Stats 2012-02-28T13:00:00Z http://support.sas.com/rnd/app/video/index.html#QC?utm_medium=RSS&utm_source=Support_Stats Bob Rodriguez describes some of the highlights of SAS/QC 9.3.  He describes the new fitted distributions that are available with the CAPABILITY procedure, new procedures for multivariate process monitoring, and updates to the RELIABILITY procedure Tue, 28 Feb 2012 13:00:00 GMT http://support.sas.com/rnd/app/video/index.html#QC?utm_medium=RSS&utm_source=Support_Stats 2012-02-28T13:00:00Z http://support.sas.com/resources/papers/proceedings11/329-2011.pdf?utm_medium=RSS&utm_source=Support_Stats <p>Find out how to extend the models available in SAS High-Performance Forecasting by creating custom repositories, taking advantage of external models, and adding user-defined models.</p> Tue, 28 Feb 2012 13:00:00 GMT http://support.sas.com/resources/papers/proceedings11/329-2011.pdf?utm_medium=RSS&utm_source=Support_Stats 2012-02-28T13:00:00Z http://support.sas.com/documentation/cdl/en/statug/63962/HTML/default/viewer.htm#statug_templt_a0000000059.htm?utm_medium=RSS&utm_source=Support_Stats Users often want to modify the survival plots from the LIFETEST procedure. The changes range from changing the plot title to modifying the layout to adding summary statistics. The chapter "Statistical Graphics Using ODS" in the <em>SAS/STAT Users Guide</em> includes an example about customizing survival plots that shows you how to modify the PROC LIFETEST template to make such modifications Tue, 28 Feb 2012 13:00:00 GMT http://support.sas.com/documentation/cdl/en/statug/63962/HTML/default/viewer.htm#statug_templt_a0000000059.htm?utm_medium=RSS&utm_source=Support_Stats 2012-02-28T13:00:00Z http://support.sas.com/rnd/app/examples/stat/BayesMeta/new_example/index.html?utm_medium=RSS&utm_source=Support_Stats <p>This example uses the MCMC procedure to illustrate two applications of hierarchical modeling  for meta-analysis of medical studies.</p> Tue, 28 Feb 2012 13:00:00 GMT http://support.sas.com/rnd/app/examples/stat/BayesMeta/new_example/index.html?utm_medium=RSS&utm_source=Support_Stats 2012-02-28T13:00:00Z
