The test statistic of the Jarque-Bera test is always a positive number and if itâs far from zero, it indicates that the sample data do not have a normal distribution. est la moyenne de l'échantillon et This is the sort of information that can easily be looked up in the manual of whatever statistics package you're using. ( Un article de Wikipédia, l'encyclopédie libre. The JarqueâBera test statistic is also calculated from the sample skewness and kurtosis, though it is based on asymptotic standard errors with no corrections for sample size. ) Un outil web pour faire le test de Shapiro-Wilk en ligne, sans aucune installation, est disponible ici. i et If the p-value is lower than the Chi(2) value then the null hypothesis cannot be rejected. From Wikipedia, the free encyclopedia In statistics, the JarqueâBera test is a goodness-of-fit test of whether sample data have the skewness and kurtosis matching a normal distribution. {\displaystyle {\hat {\mu }}_{3}} Here, the results are split in a test for the null hypothesis that the skewness is $0$, the null that the kurtosis is $3$ and the overall Jarque-Bera test. Details. {\displaystyle {\begin{aligned}&S={\frac {{\hat {\mu }}_{3}}{{\hat {\sigma }}^{3}}}={\frac {{\frac {1}{n}}\sum _{i=1}^{n}(x_{i}-{\bar {x}})^{3}}{\left({\frac {1}{n}}\sum _{i=1}^{n}(x_{i}-{\bar {x}})^{2}\right)^{3/2}}}\\&K={\frac {{\hat {\mu }}_{4}}{{\hat {\sigma }}^{4}}}={\frac {{\frac {1}{n}}\sum _{i=1}^{n}(x_{i}-{\bar {x}})^{4}}{\left({\frac {1}{n}}\sum _{i=1}^{n}(x_{i}-{\bar {x}})^{2}\right)^{2}}},\end{aligned}}}. n Therefore, the null hypothesis cannot be rejected. i Being a poetry lover, she likes to write and read poems.
