Candisc: visualizing generalized canonical discriminant and canonical correlation analysis.
(1) Used in
CANDISC * P<0.05, **P<0.001, P<0.0001, n.s.= nonsignificative.
These analyses were conducted with the
CANDISC procedure of the Statistical Analysis System (SAS, 1989), version 6.12.
One-way ANOVA's (PROC GLM), Duncan's multiple range test, and canonical discriminant function analysis (PROC
CANDISC) were used to compare the vegetation structure between locations.
The Washington State University IBM mainframe computer version of SAS (SAS Institute, 1985) was used for most analyses:
CANDISC provided descriptive statistics and performed MANOVA, canonical discriminant analysis and calculation of Mahalanobis' distances; DISCRIM was used to produce the classification matrix.
Transformed values for each species for every census interval of every treatment were analyzed by CDA using the
CANDISC procedure in SAS (SAS Institute 1987).
We calculated Mahalanobis [D.sup.2], a multivariate measure of morphological distance based on means, between all pairs of populations using the procedure Proc
Candisc in SAS (SAS Institute 1985).
In addition, discriminant function analysis (DFA) with SAS procedures
CANDISC, STEPDISC, and DISCRIM (SAS 1985) was used to determine which linear combination of habitat variables best discriminated among nest-box grid rows.
Discriminant functions necessary (CAN) for separating age groups, and determination of their relative importance for explaining total variation, were assessed with a canonical discriminant analysis (PROC
CANDISC, SAS).
The canonical discriminant analysis was performed using the statistical SAS 9.2 software and the
CANDISC (SAS Institute, 2009) procedure.

CANDISC do programa SAS.
