 The objective of the `ConfidenceEllipse` package is to compute the coordinate points of confidence ellipses and ellipsoids for a given bivariate and trivariate normal data. The size of the ellipse and ellipsoid is determined by the confidence level, and the shape is determined by the correlation structure between the variables. The confidence level is usually chosen to be 95% or 99%, and the resulting confidence region contains the points that are expected to lie within the multivariate distribution.
