Subject: [Rd] inv.logit (package boot) (PR#2394)
Message-ID: <200212251205.NAA19295@pubhealth.ku.dk>

Submission from: (NULL) (130.225.18.176)


In package boot :

> inv.logit(800)
[1] NaN

where it should have been 1.


The problem is caused by exp(x) returning Inf when x is large.

One way of fixing the problem [there may be better ways] would be to include the
line 

out[x > 709] <- 1

in inv.logit()



Cheers Ole
