SPSS Diagnostic Accuracy Analysis
Budget: $30 – $250 USD
I have a fully coded Excel file from a retrospective dental study that compares two human evaluators with several AI-driven tools on periapical radiographs. All statistics must be run in SPSS v22 and reported by radiographic data type—here that means periapical images only. Diagnostic categories are already split by severity of condition, so every metric has to respect that structure.
The core statistics I need are: sensitivity, specificity, PPV, NPV, overall accuracy, Cohen’s kappa with 95% CIs, full ROC curves, AUC values, and formal AUC comparisons across raters and applications. I also need comparative performance tests that show where the human evaluators differ from each AI system at both the overall and severity-based levels.
Please confirm that you regularly run diagnostic accuracy studies in SPSS 22. Let me know how you would lay out the comparative tables, kappa matrices, ROC figures, and the narrative interpretation that ties everything together for publication.
Deliverables
• SPSS syntax file and output viewer
• Publication-ready tables (Word/Excel) and ROC plots (high-resolution PNG/SVG)
• Concise written interpretation highlighting significant differences and clinical relevance
If you have template examples from similar projects, feel free to mention them so I can see your typical structure.
