A command to draw the eigenvalues of the selected Eigen object(s).

Settings

Fraction of eigenvalues summed

defines whether or not fractions are plotted. Fractions f_i will be calculated for each number e_i by dividing this number by the sum of all numbers e_j: f_i = e_i / ∑_{j=1..numberOfEigenvalues} e_j.

Cumulative

defines whether or not cumulative values are plotted. Cumulative values c_i will be calculated for each number e_i by summing the first i numbers e_j: c_i = ∑_j=1..i e_j).

A scree plot can be obtained if both Fraction of eigenvalues summed and Cumulative are unchecked.
