Merging value labels into indicator variable.
I have a vaiable named NAM having value : 1,2,3,4,5,6,7,8,9. I want to
make an indicator variable that will take value 1 if NAM=7 or NAM=8 or
NAM=9. How can I do that?
I usually do: Var001<- ifelse(NAM==7,1,0) for the simplest case.

Help on indicator variables
I have two indicator variables ABS and DEFF. I want to create another
indicator variable which will take value 1 if either ABS=1 or DEFF=1.
Otherwise, it will take value 0. How can I make that?

Calculating Cumulative Incidence Function
Hello,
I have a problem regarding calculation of Cumulative Incidence Function.
The event of interest is failure of bone-marrow transplantation, which may
occur due to relapse or death in remission. The data set that I have
consists of- lifetime variable, two indicator variables-one for relapse and
one for death in remission, and the other variables are donor type (having
3 categories), disease

R crash
I have a generalized linear model to solve. I used package "geepack". When
I use the correlation structure "unstructured", I get a messeage that- R
GUI front-end has stopped working. Why this happens? What is the solution?
The r codes are as follows:
a<-read.table("d:/bmt.txt",header=T")

Cumulative Incidence Function and Pseudovalue
Hi,
I want to write own R functions for cumulative incidence function and also
for the pseudovalue of the cumulative incidence function.
Can you help me?
Tas.

Comparing Cox model with Competing Risk model
I have a competing risk data where a patient may die from either AIDS or
Cancer. I want to compare the cox model for each of the event of interest
with a competing risk model. In the competing risk model the cumulative
incidence function is used directly. I used the jackknife (pseudovalue) of
the cumulative incidence function for each cause (AIDS or Cancer) in a
generalized estimating equation. I

Confidence Interval Calculation
Hello,
I have the following r-codes for solving a quasilikelihood estimating
equation:
>library(geepack)
>fit<-geese(y~x1+x2+x3,jack=TRUE,scale.fix=TRUE,data=dat,mean.link =
"logit", corstr="independence")
Now my question is how can I calculate the confidence interval of the
parameters of the above model "fit"?
