Between/Within Variance Ratios
------------------------------------------------------------
Variable          Between SD    Within SD    B/W Ratio
------------------------------------------------------------
z_const               0.7719       0.0000          Inf
z_vary                0.3697       0.9477         0.39
------------------------------------------------------------
Note: B/W > 1.7 suggests FEVD/FEF may improve on FE
      (threshold depends on corr(z,u); see Plumper & Troeger 2007)
