Note.
GDS = Geriatric depression scale.
#ac = the number of active comparisons carried out to check the DM properties of the data.
#vi = the number of violations of DM found in these comparisons.
Crit = Critical value, calculated by summation of the coefficient values of ItemH, #ac, #vi, #vi/#ac, maxvi, sum, sum/#ac, zmax, and #zsig.
MS = Molenaar Sijtsma's ρ
