Lets call the empirical distribution function >Fn on [0,1]
and the distribution function >F on [0,1]
ks.test( )
thanks for the help

Summary help
Hi, I have fittet a gamma model, and is wondering if I can read the shape and
the scale direct from the summary

How to read the summary
How can I from the summary function, decide which glm (fit1, fit2 or fit3)
fits to data best? I don't know what to look after, so I would please
explain the important output.
> fit1 <- glm(Y~X, family=gaussian(link="identity"))
> fit2 <- glm(Y~X, family=gaussian(link="log"))
> fit3 <- glm(Y~X, family=Gamma(link="log"))
> summary(fit1)

glm fit
Hi, I try to ask here, because I hope someone will help me understand this
problem-
I have fittet a glm in R with the results
> glm1 <-

Call:
glm(formula = log(claims) ~ log(sum) * as.factor(grp), family =
gaussian(link = "identity"))

Validation errors in has_one/belongs_to relationships.
I have two objects, QuoteInput and Insured.
QuoteInput has one Insured and Insured belongs to QuoteInput.
I don''t understand what I''m seeing.
I assign an Insured to a QuoteInput. The Insured object has invalid
data.
I call save! on the quote input. QuoteInput has no validations.
I expect two things to happen - 1) an exception should be thrown,

Percent damage distribution
R version: 2.7.0
Running on: WinXP
I am trying to model damage from fire losses (given that the loss occurred).
Since I have the individual insured amounts, rather than sampling dollar
damage from a continuous distribution ranging from 0 to infinity, I want to
sample from a percent damage distribution from 0-100%. One obvious solution
is to use runif(n, min=0, max=1), but this does not seem to be

Peter,
I strongly suggest that you take a break from this email thread and
careful consider the points Chandler has made about community norms and

Chandler has been exceedingly patient with explaining why your behaviour

next steps you should take.

Convert to as.Date
Hi,
I have an vector object that looks like
DA <- c("1991q1", "1993q2")
(first quarter of 1991 etc) and I want to convert it into a date object
using as.Date(). I did this for montly data but am stumped when it comes to
dealing with quarterly data and as.Date.
Would anyone be able to help? Would be very grateful for any advice, sorry
for being such an R-newbie!

Plot inside For loop
Hi
I am plotting a set of data inside a for loop.
Is it possible to use plot in for loop without redrawing the whole
plot? Am using par(new=TRUE) but that draws on top of the previous plot.
Couldn't find any threads about the topic.
Thanks

How to get JRI to work from my NetBeans

[LLVMdev] DIBuilder - what's with the null compile units?
Just a follow up on this - I am still having problems, I never did figure
out a solution. (I've been running with debug off for the last month so that
I could get work done.)
Here's what I am seeing: I am definitely calling DIBuilder::finalize(). I
even put a debug print statement right after it, so that I could be sure
that the code was being executed. I also insured that it was getting

Deleting rows based on identity variable
I have created this data frame to help illustrate my problem.

Question re model development
Dear Sir/Madam
I'm trying quite a long shot here...
I have used R previously, and would just like to know if any software/model
has been designed which will allow me to project the future risk profile of
a group of insured lives (by factors such as age, gender etc.), based on
past and exisiting risk profiles of the covered lives? If you could point me

Problem with loading rJava in R
Hello.

and get the following error message even though the mentioned .dll file is
located at the directory listed in the error message. I have tried to
uninstall and reinstall the package but that does not resolve the problem.
Then uninstallation and re-installation of R did not resolve the issue
either. Any suggestions are
