MedCalc: Powerful statistical application for biomedical sciences

If you work in the biomedical field and often need to generate statistics from tons of data you’ll probably enjoy working with MedCalc.

This highly useful piece of software comes with a built-in spreadsheet that can include as many as 10,000 rows. Missing data is handled appropriately and import is supported for various file formats like Excel, Dbase, Lotus, SPSS, DIF, SYLK and text.

The area under the curve is calculated with a 95% confidence interval and standard error. You can choose threshold values in the dot diagram and the corresponding specificity and sensitivity is automatically calculated.

ROC curves are compared based on calculating the difference between the areas under the curves using standard error, 95% confidence interval and P-value.
