Suncal Web Interface
The Suncal-Web interface currently provides these tools as a beta-test:
Suncal 2.0 Apps
- Measurement Decision Risk Calculator: Calculate global and specific risk, probability of conformance, and generate risk curves.
- End-to-end Measurement Quality Assurance:
Suncal 1.x Apps
- Uncertainty Propagation: GUM and Monte Carlo Risk Propagation
- Distribution Explorer: Sample from probability distributions and combine using Monte Carlo (typically for training purposes).
- Student T Calculator: Calculate coverage factor, level of confidence, and degrees of freedom
- Units Converter: Convert between measurement units
- Decision Risk Calculator (simple): Calculate probability of false accept and reject based on Test Uncertainty Ratios
- Decision Risk Calculator: Calculate probability of false accept and reject using arbitrary probability distributions
- Decision Risk Curves: Generate plots of decision risk versus guardbanding, in-tolerance probability, or TURs
- Decision Risk Probability of Conformance: Plot the probability of conformance versus measured value
Additional web implementations of features from the full Suncal package are in development.
About
The Suncal-Web 1.x interface runs the same back-end code as the full desktop version, but using a pyscript-based user interface. All data and calculations stay in your browser. Source code for this website and the web interface can be found on github. The Suncal 2.0 apps have been re-built in Rust for performance and deployability. Source in github.
Suncal-Web is still under active development and beta testing.
