Cramer-von Mises normality test
Hi, this is my first help request so please bear with me.
I've been running some normality tests using the nortest package. For
some of my datasets the Cramer-von Mises normality test generates an
extremely high probability (e.g., 1.637e+31) and indicates normality
when the other tests do not. Is there something I'm misunderstanding
or potentially a bug in the code?
Below are the

normality testing with nortest
I don't know from the nortest package, but it should ***always***
be the case that you test hypotheses
H_0: The data have a normal distribution.
vs.
H_a: The data do not have a normal distribution.
So if you get a p-value < 0.05 you can say that
***there is evidence***
(at the 0.05 significance level) that the data are not from a
normal distribution.
If the nortest package does

Minor bug in lillie.test from nortest package (PR#9784)

R-Help
Respected Sir
I am a very new user of R. I want to ask a question about "the nortest
package". In this package how we can write the code of ad.test, cvm.test,
ks.test for other distributions like GEV, GPA etc.
I request you to please guide to me.
Kind Regards

two sample Cramer-von Mises test
Hello list,
Is there any function in some package can calculate two sample Cramer-von
Mises test statistic? I searched around and only find one sample version
cvm.test() in nortest package.
thanks,

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?
Regards,
Kwabena.

Call connected, cannot hear or speak - $20 for fix
I am able to get this script to dial, but I am unable to talk or hear
anything. The script asks for the number to call and the the caller id to
display (if user is not at their normal extension). Once submitted, the
external extension receives a call, once answered the call is then placed to
the dentition number.
The script works as the call is place, but I cannot hear or say anything.

GLMNET AUC vs. MSE
Hello -
I am using glmnet to generate a model for multiple cohorts i. For each i, I
run 5 separate models, each with a different x variable. I want to compare
the fit statistic for each i and x combination.
When I use auc, the output is in some cases is < .5 (.49). In addition, if
I compare mean MSE (with upper and lower bounds) ... there is no difference
across my various x variables, but

Error: could not find function "ad.test"
Hi,
I'm trying to run an anderson-darling test for normality on a given variable
'Y':
ad.test(Y)
I think I need the 'nortest' package, but since it does not appear in any of
the Ubuntu repositories for 2.10.1, I am wondering if it goes by the name of
something else now?
Thanks

Hi there,
I am trying to perform different normality tests in R. I have no problem
when I use Shapiro.test( ). However, when I try to use any normality
tests from the Nortest package, I kept getting this error " Error in
read.table(source, header = T, fill = T) :
'file' must be a character string or connection". I have no idea
why because there was no problem with

Test Normality
Good Night
I made different test to check normality and multinormality in my dataset,
but I don´t know which test is better.
To verify univariate normality I checked: shapiro.test, cvm.test, ad.test,
lillie.test, sf.test or jaque.bera.test and
To verify multivariate normal distribution I use mardia, mvShapiro.Test,
mvsf, mshapiro.test, mvnorm.e.
I have a dataset with almost 1000 data and 9

Competing with one's own work (Prof. John C Nash)
John, thanks for starting (or restarting) this thread.? I'd like to
add to the discussion with another concrete example, about as simple
as it gets, which may help focus at least part of this discussion.
I have worked with Taylor Arnold to implement a method developed in
Conover (1972) for Kolmogorov-Smirnov goodness-of-fit tests for
discrete distributions (one-sample only).? We needed this

modification of the function ecdf
Dear R users,
I am trying to minimize the distance between my data points and theoretical
gamma distribution over shape and scale parameters. the function "mde" from
actuar package does it for empirical distribution function and theoretical
gamma distribution. However, I would like to minimize the distance by using
only the data between 0.1 and 0.9 quantiles. I cannot use ecdf in this

Dear All,
I am using roptest function of package "ROptEst" (Kohl and Ruckdeschel

the RMX estimator.
Then I am trying to Plot the data in the form of a histogram and add the

detect if data is normal or skewed (without a boxplot)
Hello all:
Is there a way to detect in R if a dataset is normally distributed or skewed without graphically seeing it? The reason I want to be able to do this is because I have developed and application with Visual Basic where Word,Access and Excel "talk" to each other and I want to integrate R to this application to estimate confidence intervals on fish sizes (mm). I basically want to
