/spss-extensions/index.htmlSPSS is a versatile and powerful program for management and statistical analysis of complex data. Especially its “point and click” user interface for data preparation and statistical tests (besides the extensive options for manual coding in syntax) makes it intuitive and user-friendly for those that don’t perform data analysis on a very regular basis. Despite its comprehensiveness, not all common analysis procedures or tests are covered in the user interface. Below are some custom dialogues that I developed for several analyses I frequently use in my outcomes research and psychometric work. The following dialogs can be installed in SPSS and allow you to perform these analyses using the familiar SPSS dialog boxes:Hugoen-usMon, 22 Dec 2025 00:00:00 +0000/spss-extensions/auc_serial-measurements/index.htmlMon, 22 Dec 2025 00:00:00 +0000/spss-extensions/auc_serial-measurements/index.htmlSPSS custom dialog bundle for computing the area under the curve of serial measurements using the trapezium rule, as described by Matthews et al.
