====== Metric Compute 95Confidence Ellipse ======

Compute the 95 % confidence ellipse in 2 or more dimensions.

The smallest ellipse that will cover 95 % of the data points.

Compute the area or volume of an ellipse based on PCA. Does not require all vertices to be present for all frames.

Resulting Signal

Frame 1 contains volume and average value
Starting at frame 2
one frame for each dimension containing the eigenvalue and eigenvector (e.g. scale and unit vector)
