Small N Stats Demand Curve Analyzer (Qt)
Small N Stats Demand Curve Analyzer is a Qt-based application that communicates with R to easily facilitate complex calculations required of behavior economic (BE) scientists.
- Non-linear model fittings (John Nash's modified LM optimizer, specificially suited for BE models)
- Multiple Models available (Hursh & Silberberg's Exponential Model, Koffarnus et. al.'s Exponentiated model)
- Easily imports common file formats into the application's spreadsheet (.xlsx)
- Full range of BE outcome metrics (empirical and derived), saveable in common spreadsheet file formats
