TABLE 6. .Summary of univariate MRPP P-values for HIPLEX-I primary response variables.

CIC2, CIC5, CCR5, PIC8, MVD8, A WC8, TFPI, TFE,
TIP A, TIPR, AER, and RERC. The listed order of
the previously listed primary response variables cor-
responds to the chain of events prescribed by the phys-
ical hypothesis (Smith et al., 1984).
In order to mitigate the potential effect of a relatively
few extreme values, the individual response variables

were coded as rank order values from below, i.e., the
N response variable values were converted to integers
from 1 to N in correspondence with their observed
magnitudes. The rank order values associated with any
two response variables are commensurate with one
another by virtue of their construction, i.e., each re-
sponse variable is rescaled from 1 to N. On the other
