ConfidenceEllipse 1.1.0
- Added
distribution
parameter to the
confidence_ellipse()
and confidence_ellipsoid
functions allowing users to choose between "normal"
and
"hotelling"
(Hotelling’s T²) distributions for ellipse
calculation.
- Enhanced statistical rigor: Hotelling’s T² distribution now properly
accounts for parameter estimation uncertainty in small sample
sizes.
- Updated documentation with detailed explanations of distribution
choices and robust methods.
- Added recommendations for parameter selection based on sample size
and data characteristics.
- Change name of
transform_data
helper function to
transform_2d
and transform_3d
for clarity and
consistency.
ConfidenceEllipse 1.0.0
- Added
robust
parameter to the
confidence_ellipse()
and confidence_ellipsoid
functions enabling robust estimation methods using 1-step M-estimator
with biweight psi function for location and Minimum Covariance
Determinant (MCD) estimator for scale.
- Improved handling of outliers and non-normal data through robust
estimation options.
- Enhanced documentation with examples demonstrating the use of robust
methods.
- CRAN release with comprehensive vignettes and examples.
ConfidenceEllipse 0.2.1
- Improved code of
transform_data
helper function.
ConfidenceEllipse 0.2.0
- Added
transform_data
helper function to streamline data
transformation processes.
ConfidenceEllipse 0.1.4
- Modified package logo to include a more visually appealing
design.
- Updated package description to better reflect the functionality and
features of the package.
ConfidenceEllipse 0.1.3
- Cleaned up code and improved performance of
confidence_ellipse()
and
confidence_ellipsoid()
functions.
ConfidenceEllipse 0.1.2

confidence_ellipse()
function for 2D
confidence ellipse calculations.
- Introduced
confidence_ellipsoid()
function for 3D
confidence ellipsoid calculations.
ConfidenceEllipse 0.1.1
- Fixed bug in
confidence_ellipse()
function where the
conf_level
parameter was not being correctly applied.
ConfidenceEllipse 0.1.0
- Initial release of the ConfidenceEllipse package.
