Regress+ is a user-friendly, state-of-the-art tool for mathematical modeling.
General
1. Simple (univariate) mathematical modeling
2. Data:
-- deterministic (regression)
-- stochastic (random variates)
3. Up to 2,147,483,647 points (minimum 7)
4. Robust goodness-of-fit testing
5. Bootstrap confidence Intervals (90, 95, and 99 percent) for
-- parameters
-- stochastic-model goodness-of-fit metrics
6. Bootstrap methodology (where appropriate):
-- BCa technique (state-of-the-art)
-- percentile technique
-- tunable precision
7. Optional "freezing" of initial estimate(s) for any parameter(s)
8. Choice of optimization criterion
9. No hidden assumptions anywhere:
-- no approximations, apart from those common to sampling and bootstrapping generally
-- no data transformations of any kind
10. "Smart" dialogs to run unattended and/or in the background
11. Textfile input (may contain unlimited comments)
12. Both text and graphical output
13. One keystroke makes a Plot (may be saved as a PICT)
14. Extensive documentation (in PDF)
