Analyze data normality effortlessly with our Jarque-Bera Test Calculator. Quickly determine if your dataset's skewness and kurtosis deviate significantly from a normal distribution. Ideal for researchers, students, and financial analysts evaluating assumptions for statistical models. Calculate the JB statistic and interpret results instantly.
Formula:
The Jarque-Bera (JB) test statistic is calculated using the following formula:
JB = (n/6) * [S2 + (1/4)*(K-3)2]
- n: The number of observations (sample size).
- S: The sample skewness.
- K: The sample kurtosis.
