How to make infectious diseases look better

The Wall Street Journal recently published some graphs about seven infectious diseases, and I tried using SAS to improve the graphs ... it's a veritable infectious disease (graph) bake-off!

Create an array of matrices in SAS

The SAS DATA step supports multidimensional arrays. However, matrices in SAS/IML are like mathematical matrices: they are always two dimensional. In simulation studies you might need to generate and store thousands of matrices for a later statistical analysis of their properties. How can you accomplish that unless you can create
