I am new to R and am trying to fit a survival curve with a weibull
hazard function to a set of data giving the probability of survival to
age x, given the year of birth, in the form:
Probability of survival:
Birth year
1980 1981 ... 2003
.2 0.90 0.89 ... 0.87
1 0.80 0.81 ... 0.79
age 2 0.75 0.74 ... 0.73
3 0.70 0.69 ... 0.68
5 0.50 0.49 ... 0.43
10 0.30 0.31 ... 0.26
I would like to be able to fit a curve to each birth cohort, extrapolate
the curve a few years and be able to create a plot of the survival
curves.
Am having some trouble with working out how to do this in R and would be
most grateful for a few pointers.
Many thanks for any help
Rich
