What does a high Jarque-Bera mean?
In general, a large J-B value indicates that errors are not normally distributed. For example, in MATLAB, a result of 1 means that the null hypothesis has been rejected at the 5% significance level. In other words, the data does not come from a normal distribution.
How do you do Jarque-Bera in Excel?
Use the following steps to perform a Jarque-Bera test for a given dataset in Excel….Jarque-Bera test in Excel
- Step 1: Input the data. First, input the dataset into one column:
- Step 2: Calculate the Jarque-Bera Test Statistic. Next, calculate the JB test statistic.
- Step 3: Calculate the p-value of the test.
What is p value in Jarque Bera test?
The test p-value reflects the probability of accepting the null hypothesis. If it’s too low then you reject it. You must set the confidence level, for instance α=5%, then reject the null if p-value is below this α. In your case p-value is over 50%, which is too high to reject the null.
What does the Ramsey Reset test do?
In statistics, the Ramsey Regression Equation Specification Error Test (RESET) test is a general specification test for the linear regression model. More specifically, it tests whether non-linear combinations of the fitted values help explain the response variable.
How do you tell if my data is normally distributed Excel?

How is the Jarque-Bera test used in statistics?
Jarque–Bera test. In statistics, the Jarque–Bera test is a goodness-of-fit test of whether sample data have the skewness and kurtosis matching a normal distribution. The test is named after Carlos Jarque and Anil K. Bera. The test statistic is always nonnegative.
How did Carlos Jarque and Anil Bera get their statistic?
The statistic was derived by Carlos M. Jarque and Anil K. Bera while working on their Ph.D. Thesis at the Australian National University. According to Robert Hall, David Lilien, et al. (1995) when using this test along with multiple regression analysis the right estimate is:
What’s the motivation for the J-B test?
Let’s take a look at them. What’s the Motivation for the Test? The basic idea behind the J-B test is that the normal distribution (with any mean or variance) has a skewness coefficient of zero, and a kurtosis coefficient of three. (That is, it has zero “excess kurtosis”.)
Which is the correct definition of the test statistic JB?
The test statistic JB is defined as where n is the number of observations (or degrees of freedom in general); S is the sample skewness, K is the sample kurtosis :
