Comparing two documents in the index
I want to compare two documents in the index (i.e. retrieve the cosine
similarity/score between two documents term-vector''s). Is this possible
using the standard Ferret functionality?
Thanks in advance,
Jeroen Bulters

Overall p-value from a factor in a coxph fit
Hi all.
If I run the simple regression when x is a categorical variable ( x <-
factor(x) ):
> MyFit <-coxph( Surv(start, stop, event) ~ x )
How can I get the overall p-value on x other than for each dummy
variable?
> anova(MyFit)
does NOT provide that information as previously suggested on the list.
All the best,
Kare
