Ellipse: Functions for Drawing Ellipses and Confidence Regions

Various routines for drawing ellipses and ellipse-like confidence regions, implementing plots from Murdoch and Chow (1996). The dataset also includes routines for profile plots described in Bates and Watts (1988). It was ported to R by Jesus M. Frias Celayeta.

Use Cases

• Visualizing confidence regions for parameter estimates based on the Murdoch and Chow method.
• Creating profile plots for nonlinear regression models based on the Bates and Watts method.
• Implementing statistical graphics for publication or model diagnostics using the provided routines.

Strengths

• Implements established statistical visualization methods from peer-reviewed literature.
• Provides routines for both confidence ellipses and profile plots, covering two common visualization needs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
