# Suncal Web Interface

The Suncal-Web interface currently provides these tools as a beta-test:

- Uncertainty Propagation: GUM and Monte Carlo Risk Propagation
- 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
- 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

Additional web implementations of features from the full Suncal package are in development.

## About

The Suncal-Web 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.

Suncal-Web is still under active development and considered in beta testing.

### Limitations

Some features are only available in the desktop version at this time, including:

- Loading and saving calculation setup
- Reverse and swept uncertainty propagation
- Analysis of Variance calculations
- Calibration interval analysis
- Curve fitting uncertainty analysis
- Combining the results of different calculations
