MedCalc Statistical Software

MedCalc is a statistical software package designed for the biomedical sciences. Its integrated spreadsheet can be customized to hold up to 100,000 rows, making it ideal for data-intensive analysis. The program handles missing data accurately and includes reliable date arithmetic functionality, which is essential in medical research.

One of the key features of MedCalc is its ability to import files from various formats, including Excel, SPSS, DBase, Lotus, SYLK, DIF, and text formats. The software comes with detailed online help, as well as a complete user manual in PDF format that's available on the web.

It also includes a complete module for Receiver Operating Characteristic (ROC) curve analysis, which calculates sensitivity, specificity, likelihood ratios, and positive and negative predictive values for all possible threshold values. The program calculates the area under the curve (AUC) with its standard error and 95% confidence interval. Furthermore, threshold values can be selected in an interactive dot diagram with automatic calculation of corresponding sensitivity and specificity. Comparing ROC curves includes calculation of the difference between the areas under the curves, with standard error, 95% confidence interval, and P-value.

MedCalc is certified for Windows 7 and provides a free trial for users to test it out before purchase. In summary, MedCalc is a comprehensive software tool for biomedical researchers who require robust statistical analysis, with intuitive features and tools to handle large datasets.
