Hey! Am an undergrad student very new to MATLAB, and I was trying to run the Jarque-Bera test!

The computer has given me this output:

Error using jbtest (line 74)

Input X must be a vector of real values.

I am not sure how to interpret this! I would be very grateful for any guidance!

Guessing here, since we don’t know what ‘x’ is.

It appears that ‘x’ may be complex. If so, your best approach is likely to use the real (link) function to extract the real parts.

Hey Star Strider,

Thanks so much for your reply!

In response to another thread I posted, I tried the command below:

One option is to use the table2array (link) function to extract your table data to an array kstest can use.

Once I did this, I then used the [h,p,jbstat,critval] = jbtest(A), as I had named the Array 'A'!

The test then worked!
