Its methods include regression, ANOVA, meta-analysis, survival analysis, exact tests, sample-size estimation, and Bayesian analysis, with scripting support. The data interface follows an Excel-like layout, while reports use a simple word-processor style. A statistics guide and context-sensitive help explain results and reports. StatsDirect imports Microsoft Excel files (.xlsx and.xls), common spreadsheet data, and formatted or plain text; it can write Excel files and reports in RTF or HTML. The maker describes links with Microsoft Excel and incorporation of R for advanced use. The software emphasizes confidence-interval inference and uses exact profile-likelihood methods wherever practical.
