The first of these three models used a single indepen-
dent variable, stage. The regression was significant
F (5, 136) = 5.92, p = .0001. The squared multiple corre-
lation coefficient equaled .18.
The second model used sex and stage as independent
variables. These findings are summarized in Table 18.

The regression was also significant at the .05 level. The
partial regression coefficients of both independent variables
were also significant at the .05 level.
Model two, with sex and stage as independent variables,
was selected for use in predicting the survival of rectocolon
