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 [[alternative HTML version deleted]]

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? I looked at the skewness and...

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...

Dear all, i have the question about the using of Jarque-Bera Test by using R. The question is that I do not have in my package "ts" this test and can not obtain any information in the help-file. Could you help my? Where could I download the package and which one, to use the Jarque-Bera Test? Thank You, Susan ----------------------...

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...

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 what I don't understand...

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){ print(jarque.bera.test(loghozamok[((20*(i-1))+1):(20*(i+11))]))}

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? platform i386-pc-mingw32 arch...

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 [[alternative HTML version deleted]]

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.

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 nice to report the values of 8 different tests on a report. One n...
