How to overlap two density plots?
Hi,
How can I overlap two density plots?
A <- c(8,10,10,11,11,11,12,12,12,12,11,11,11,10,10,7)
B <- c(11,13,13,14,14,14,15,15,15,15,14,14,14,13,13,10)
plot(density(A))
plot(density(B))
Regards,
Emre
P.S. There's a overlap.density function in package DAAG
Is there another way to do this?

FW: Time Series
Hello!
What is the error message, please?
At first glance, you are using the "ts" function. That doesn't work for
hourly frequency.
You may want to create a zoo object.
This is Round One.
Sincerely,
Erin

FW: Time Series
Hi,
I would like to ask a question about time series.
I am trying to convert my data into time series data.
I have hourly data from ?2015-12-18 00:00? to ?2017-10-24 23:00?
I am trying the following codes but they are not working.
Could you help me out?
tseri <- ts(data ,seq(from=as.POSIXct("2015-12-18 00:00:00"), to=as.POSIXct("2017-10-24 23:00:00"), by="hour"))

Howto hide scsi or other hardware from the virtual system
Hi,
I have created a virtual system via xen and would like to strip some
unrequired virtual hardware from it.
Example: my virtual Windows system shows me a scsi PCI device (as
unknown device). I would like to get rid of it - I am only using IDE in
the virtual system.
How can I hide specific hardware from the virtual system?

How to convert List object to function arguments?
Dear R gurus,
I have a function "goftests" that receives the following arguments:
* a vector "x" of data values;
* a distribution name "dist";
* the dots list ("...") containing a list a parameters to pass to CDF
function;
and calls several goodness-of-fit tests on the given data values against
the given distribution.
That is:

Basic general statistical problem.
Hello everyone,
I'd like to have suggestions about a common basic statistical approach,
hope to be useful also for other R beginners.
When you first get some data (i.e length of river) you may want to look at its distribution.
Then you probably want to find which law follows this distribution,
and to test the goodness of the fit.
For doing this simple analysis I am writing some code

Automating binning for chisq.test()
The standard chisq.test() and fisher.test() functions, when applied to
two distributions (to determine whether the same underlying
distribution applies to both) requires one to pre-bin the
distributions.
Is there a library function (either built-in or in a package) that
acts more like the ks.test() function, in that one can simply pass the
two distributions and have it do the necessary binning as

listing all test functions in base R
Hi,
Is there a way to create a list of all statistical test functions in
base R? For example, there's t.test, ks.test, chisq.test, etc. I'd
like to create a list of these test names because I keep looking for
different tests but never know what's available. I'm thinking of a
regular expression statement but I'm not sure how this would work for
functions. Or is there a

Kolmogorov-Smirnov test, which one to use?
Hi,
I have two sets of data, an observed data and generated data.
The generated data is obtained from the model where the parameters is estimated
from the observed data.
So I'm not sure which to use either
one-sample test
ks.test(x+2, "pgamma", 3, 2) # two-sided, exact
or
two-sample test
ks.test(x, x2, alternative="l")
If I use the one-sample test I need to

Cox Regression : Spline Coefficient Interpretation?

I'm using a Cox-Regression to estimate hazard rates on prepayments.
I'm using the "pspline" function to face non-linearity, but I have no clue

Unfortunately I did not find enough information on the "pspline" function

Kolmogorov-Smirnof test for lognormal distribution with estimated parameters
Hello all,
Would somebody be kind enough to show me how to do a KS test in R for a
lognormal distribution with ESTIMATED parameters. The R function
ks.test()says "the parameters specified must be prespecified and not
estimated from the data" Is there a way to correct this when one uses
estimated data?

Test chi cuadrado de bondad de ajuste
Hola,
con vistas a docencia, me gustaría saber si hay alguna librería que
haga el test de la chi cuadrado para variables continuas, que no sean
la normal.
Lo encontré para variables discretas y para la normal. También,
obviamente, se puede hacer un pequeño programa que lo calcule "como a
mano", pero a los alumnos les obliga a entrar en detalles de
programación... :-/
La idea sería
