Steps to identify Non-embeddability 1. , 2. Negative eigenvalues have odd algebraic multiplicity, 3. Complex eigenvalues occur in non-conjugate pairs, 4. The set of eigenvalues, , lie outside the region in the complex plane, 5. – negative off-diagonals – threshold −0.1, NE =  Non-Embeddable, No. rejections of from parametric bootstrap scheme with a p-value (percentage of total tests), 1 Alignment failed to find stable estimates.
