Extrapolating Cox predicted risk
Dear all
I generated predicted risk of death for each subject in the study by
means of Cox proportional hazards model at 8 year of follow-up, a time
point at which follow-up was more than 90% complete. It is possible to
extrapolate to 10-year the predicted risk of each subjet by assuming
an exponential distribution?
Any help would be greatly appreciated.
Thanks for your consideration.

predict.*bSpline() bugs extrapolating for deriv >= 1 (PR#1473)
I've already fixed the bugs, but as with the last one, this is
not critical enough to allow breaking current R-devel's code
freeze. I hope I will have corrected it for 1.5.1..

Extrapolating values from a glm fit
Dear R-help,
I have fitted a glm logistic function to dichotomous forced choices
responses varying according to time interval between two stimulus. x values
are time separation in miliseconds, and the y values are proportion
responses for one of the stimulus. Now I am trying to extrapolate x values
for the y value (proportion) at .25, .5, and .75. I have tried several

splinefun gives incorrect derivs when extrapolating to the left (PR#13132)
This is a low priority bug that has been around for a while, but I came acr=
oss it again while alpha testing 2.8.
The resulting function for splinefun gives incorrect deriv values when x is=
less than the smallest x-value used to create the function (at least in on=
e circumstance), but does the correct thing for x greater than the largest =
x-value.
Here is an example:
