Updates
=====
Version 1.001 corrects multiple popover and action sheet bugs.
What's New in Version 1.003
Version 1.003 was recompiled against iOS 4.3.2 in the hope of eliminating a obscure bug that caused the app to crash on some iPads after updating to iOS4.3.2. Also, Version 1.003 modifies the chi-squared report for 2 x 2 arrays to show chi-squared and p with and without the Yates correction. Finally, Version 1.003 enables data set sharing though iTunes.
