Table 1

Various methods used to sample the AR in the space with respect to the values of the roots and the connected components of the AR.

Roots	AR	Grid	Sampling in ρ
	components
au	1	50 × 50	Unif. in log₁₀(ρ)
au	1	50 × 50	Unif. in ρ
r₁ > 0, r₂ > 0, r₃ > 0	2	100 × 100	Unif. in ρ

Notes. The sampling in is always uniform.
