Jarque-Bera and rnorm()
Folks,
I'm a bit puzzled by the fact that if I generate 100,000 standard normal
variates using rnorm() and perform the Jarque-Bera on the resulting vector,
I get p-values that vary drastically from run to run. Is this expected?
Surely the p-val should be close to 1 for each test?
Are 100,000 variates sufficient for this test?
Or is it that rnorm() is not a robust random number generator?

Jarque-Bera test
Hello,
I'm so confused why I can't run Jarque-Bera test on my data. I have 9968
observation and I want to run Jarque-Bera test on them, but no matter how
hard I am trying I can't get it work. please let me know what should I do.
Best,
Kiana

Diagnostic Tests: Jarque-Bera Test / RAMSEY
Hello R-Users,
The following questions are not R-technical, but more of general statistical
nature.
1. NORMALITY
I built a normal linear regression model and now I want to check for the
residual normality assumption. If I check the distribution graphically and
look at the descriptive characteristics (skewness and kurtosis are below 1),
I would confirm that the residuals are normally

Is there a way to specify different significance levels in jarque.bera.test()?
Dear List:
I am trying to understand how to use the
jarque.bera.test() function of the "tseries" package.
A numeric vector or time series seems to be the only
argument required. What is the default significance
level for rejecting the null of normality?
Is there a way to specify different significance
levels?

Jarque-Bera test and Ljung-Box test for multivariate time series
Hi!
I know that there is function in fBasics package for univariate Jarque-Bera
test and a funtion for univariate Ljung-Box test in stats package. But I am
wondering if there is a function somewhere to do the tests for multivariate
time series?
Thanks,
John

help on jarque test
Hi all,
I used the function jarque.test (in the moments package) on my data set and
I obtained something like this:
Jarque-Bera Normality Test
data: x
JB = 4.8381, p-value = 0.089
alternative hypothesis: greater
or
Jarque-Bera Normality Test
data: x
JB = 2.6018, p-value = 0.2723
alternative hypothesis: greater
I cannot understand this. Please, someone can help me?
thank you

How can I test if time series residuals' are uncorrelated ?
Ok I made Jarque-Bera test to the residuals (merv.reg$residual)
library(tseries)
jarque.bera.test(merv.reg$residual)
X-squared = 1772.369, df = 2, p-value = < 2.2e-16
And I reject the null hypotesis (H0: merv.reg$residual are normally
distributed)
So I know that:
1 - merv.reg$residual aren't independently distributed (Box-Ljung test)
2 - merv.reg$residual aren't indentically

confused about names()
Hi all .. there is no doubt a simple answer to this, but it eludes me.
In the first session below ( with jarque.bera.test) you will see that
p.value prints with a name of X-squared .
This is easily fixed by changing the source to assign a
more appropriate name - no name is assigned in the source listing
below (the original source code of jarque.bera.test() from tseries).. but

jarquebera_test_results
Hi!
I got a loop where i print out the results of Jarque Bera tests, but I
have to put, the p-values in a vector. Can you help me how to do it in
an effective way and not just typing in the results to a vector? Thanks
a lot, here is the code:
for(i in 1:60){

normality tests
Hi all,
apologies for seeking advice on a general stats question. I ve run
normality tests using 8 different methods:
- Lilliefors
- Shapiro-Wilk
- Robust Jarque Bera
- Jarque Bera
- Anderson-Darling
- Pearson chi-square
- Cramer-von Mises
- Shapiro-Francia
All show that the null hypothesis that the data come from a normal
distro cannot be rejected. Great. However, I don't think it looks

Normal tests disagree?
If I have data that I feed into shapio.test and jarque.bera.test yet they seem to disagree. What do I use for a decision?
For my data set I have p.value of 0.05496421 returned from the shapiro.test and 0.882027 returned from the jarque.bera.test. I have included the data set below.
Thank you.

normality tests [Broadcast]
The normality of the residuals is important in the inference procedures for the classical linear regression model, and normality is very important in correlation analysis (second moment)...

Let me firstly thank the R Core Team for their tremendous efforts in

I source compiled R 1.8.0 for windows with ATLAS (source compiled, too).
Everything works fine and R is running flawlessly! However, running "make

Dear Federico,
see:

They are the most common tests used for normality

png() and/or jpeg(): line missing by using box(which="outer")
Dear R list,
I do encounter the following problem by generating either a png-file
(example below) or a jpeg-file:
By employing 'box(which="outer")' a box is drawn, except for the right line.
If I generate the plot without the 'box(which="outer")', a line at the
bottom in the graphics file still appears. However, both plots are displayed
correctly in the R
