Does psm::Surv handle interval2 data?
Does Surv in psm handle interval2 data? The argument list seems to indicate it does but I get an error.
Thanks,
Chris

PSM function in Design package (PR#6525)
Full_Name: Oleg Raisky
Version: 1.8.1
OS: Windows 2000
Submission from: (NULL) (63.246.203.107)
This is a completely fresh R install. I'm trying to use Design package. Every
time I run the first example for psm() I'm getting an error <<couldn't find
function "survreg.fit">>. However, survreg.fit does exists in the search path.
Is there something I can do to fix

Missing Values in Design Package
I am using psm to fit a survival model with a dataset that has missing
values,
e.g., DS <-psm(Surv(los,DSCHRG) ~AGE + SEX + ACUITY,
data=LOS,dist='weibull',x=TRUE,y=TRUE)
and I notice that when I look at the output there are 0 missing values and
when I use the summary function
e.g., summary(DS) plot(summary(DS))
the missing values are showing up as a category
e.g., for Sex

lmer p-values for fixed effects missing
I am trying to replicate the repeated measures example from Dr.Faraway's book
(Extending the linear model with R) as follows:
data(vision)
vision$npower <- rep(1:4,14)
mmod <-lmer(acuity~power+(1|subject)+(1|subject:eye),vision)
When I look at the fixed effects p-value, it is missing. Am I missing
something here?
Thanks.

Propensity Score Matching
Hola chic en s, alguien con experiencia en propensión score matching?
Planteo duda: Clasicamente el PSM se ha utilizado en un intento de homogeneizar cohortes de enfermos quienes han estado ?expuestos? a un tratamiento x Vs aquellos que no han estado expuestos (no expuestos). Esto aplica para medicamentos o procedimientos quirúrgicos o no.
Bien, En algún articulo he leído que el PSM se puede

Survreg/psm output
Dear R-listers,
I know that there have been many, many posts on the output from
Survreg. To summarise what I have read, Scale is 1/shape of the
Weibull which is also the standard deviation of the normal
distribution which is also the standard deviation of the log survival
time and Intercept is log(scale). I also know that the hazard
function can be calculated from the output to give something

synaptics problem
Hi,
I've recently installed FreeBSD 6.3, and I've got a problem with
synaptics.
I've installed it, followed the pkg-message :

It works, dmesg gives :

psm0: [GIANT-LOCKED]

NAMESPACE and imports
I am cleaning up the rms package to not export functions not to be called
directly by users. rms uses generic functions defined in other packages.
For example there is a latex method in the Hmisc package, and rms has a
latex method for objects of class "anova.rms" so there are anova.rms and
latex.anova.rms functions in rms. I use:

Can compressed music sound better than uncompressed?
I quote from "Principles of Digital Audio" by Ken C. Pohlmann:
"Because perceptual coders tailor the coded signal to the ear's acuity, they
similarly tailor the required response of the playback system itself. Live
music does not pass through amplifiers and loudspeakers, it goes directly to
the ear. But recorded music must pass through the playback signal chain. Much

Parametric survival models with left truncated, right censored data
Dear All,
I would like to fit some parametric survival models using left
truncated, right censored data in R. However I am having problems
finding a function to fit parametric survival models which can handle
left truncated data.
I have tested both the survreg function in package survival:
fit1 <- survreg(Surv(start, stop, status) ~ X + Y + Z, data=data1)
and the psm function in package

mouse problems [A4 Tech OP-3D]
After some poking into psm.c code I've got some results.
First, for the archives, debug.psm.loglevel tunable is much more useful
than a verbose boot for debugging PS/2 mouse issues. A good value is 2.
Second, I fiddled with various probe methods to force them to
"recognize" my mouse (by loosening their checks) and found out that the
mouse works perfectly if it is treated as

survival parametric question
Hi to all,
I am working on design package using survival function.
First using PSM and adopting a weibull specification for the baseline hazard , I have got the following results(since weibull has both PH and AFT propreties ,in addition I have used the PPHSm command):
Value Std. Error z p

FYI about my Mona Vie business venture
Asterisk work does not pay all of my bills, so I have joined up with a company that has a very good payment plan.
I have recently become a Mona Vie Independent Distributor.

Weibull survival regression
Dear R users,
Please can you help me with a relatively straightforward problem that I
am struggling with? I am simply trying to plot a baseline survivor and
hazard function for a simple data set of lung cancer survival where
`futime' is follow up time in months and status is 1=dead and 0=alive.
Using the survival package:

Nomogram with multiple interactions (package rms)

I'm facing the following problem :
A cox model with my sex variable interacting with several continuous variables : cph(S~sex*(x1+x2+x3))
And I'd like to make a nomogram. I know it's a bit tricky and one mights argue that nomogram is not a good a choice...
I could use the parameter interact=list(sex=("male","female"),x1=c(a,b,c))... but with rcs or pol
