Correlation statistics and linear regression parameters and predictions. Plots of raw and studentized residuals. The app comes with several example datasets preloaded, which you can directly open in the app to explore the app's various feature with a real dataset. You can also upload your own datasets to the phone by simply sending a csv file as an email attachment (or placing it in iCloud).
