In reply to Rick Wicklin.

Dear Rick Wicklin,

If X is a multivariate distribution, the sample size is 10, the number of variables is 3, the simulating data from multivariate gamma distribution (Wishart distribution). The result is 9 columns and 10 observations. Which x1, x2 and x3 are used for testing multivariate normal distribution by jaque-bera test.

What is x1,x2,x3 in 9 columns?

Thank you in advance and Best Regards,

Mantana Seeno
