I don't. Could there be a G3/G4 issue?

survreg (survival) reports erroneous results for left-censored data (PR#2287)
Full_Name: Tim Cohn
Version: 1.6.1
OS: Macintosh OS X
Submission from: (NULL) (130.11.34.250)
The Mac version of survreg does not handle left-censored data correctly (at
least the results are not what I get doing it other ways, and they are not the
same as I get running R 1.6.1 in Windows 98se; the Windows 98 results are
correct). On the windows version of R 1.6.1.

R-1.6.0
I have build R-1.6.0 on Jaguar (actually on 10.2.2), using gcc 3.1
from Apple, g77 3.1 from fink, ATLAS from fink. It passes all
checks OK.
I also re-compiled the 233 packages listed below
with the same setup. I have NOT tested all these
packages in any detail. A tar.gz file with the whole /usr/local/lib/R
will be on ftp://gifi.stat.ucla.edu on Tuesday. It will NOT include
anything from fink

R-1.6.1 with gcc-3.3
This is probably only interesting to zero or one or two persons.
gcc-3.3 from Apple's CVS does not handle the -bundle flag properly.
I had to hack configure.ac, which now has

R-1.6.0 for Darwin
I don't think it is necessary to put binary versions of the Darwin/X11
version on CRAN any more. The current sources compile without
problems on both Mac OS X 10.1 and 10.2, using either gcc/g77 2.95.2 or
gcc/g77 3.1, or f2c. It seems to me that
if you are using R from the command line, using X11, that you are
sophisticated enough to install the tools below. And, if you want

Survreg(), Surv() and interval-censored data
Can anybody give me a neat example of interval censored data analysis codes in R?
Given that suvreg(Surv(c(1,1,NA,3),c(2,NA,2,3),type="interval2")~1)
works why does
survreg(Surv(data[,1],data[,2],type="interval2")~1)
not work where
data is :
T.1 T.2 Status

survreg() provides same results with different distirbutions for left censored data
Hello,
I'm working with some left censored survival data using accelerated failure
time models. I am interested in fitting different distributions to the data
but seem to be getting the same results from the model fit using survreg
regardless of the assumed distribution.
These two codes seem to provide the same results:

interval-censored data in survreg()
I am trying to fit a lognormal distribution on interval-censored
data. Some of my intervals have a lower bound of zero.
Unfortunately, it seems like survreg() cannot deal with lower
bounds of zero, despite the fact that plnorm(0)==0 and
pnorm(-Inf)==0 are well defined. Below is a short example to
reproduce the problem.
Does anyone know why survreg() must behave that way?
Is there an alternate

Survreg(), Surv() and interval-censored data
Can survreg() handle interval-censored data like the documentation
says? I ask because the command:
survreg(Surv(start, stop, event) ~ 1, data = heart)
fails with the error message
Invalid survival type
yet the documentation for Surv() states:
"Presently, the only methods allowing interval censored data are
the parametric models computed by 'survreg'"

I meant there is no native (Aqua) version of GTK yet (there is
wxWindows and Qt and Tk, so
possibly GTK will follow). The X11 version of RGtk works for me too. I
agree with your
diagnosis of the GUI problem.

R version on gifi
Pretty soon, hopefully, the RAqua version will make the Darwin/X11
version unnecessary. In the meantime, for convergence, I'll modify the
Gifi
version in various ways.
-- It's 1.7.1
-- It no longer supports gnome
-- It still uses Tcl/Tk for X11 (using 8.5 from CVS)
!! It no longer uses anything from fink (readline and dlcompat

Interval censored Data in survreg() with zero values!
Hello,
I have interval censored data, censored between (0, 100). I used the
tobit function in the AER package which in turn backs on survreg.
Actually I'm struggling with the distribution. Data is asymmetrically
distributed, so first choice would be a Weibull distribution.
Unfortunately the Weibull doesn't allow for zero values in time data,
as it requires x > 0. So I tried the

BLAS/Lapack on OS X
R-devel has the --with-lapack flag for configure. If you build R with

then the build goes through, using the native optimized BLAS and
Lapack in /System/Library/Frameworks/vecLib.framework. Also, it
works, in the sense that it does eigenvalue problems correctly.
