 I have a translation question about "Choi meta-tests"
 Is meta here the same as in metadata (data about data). In other
 words, do meta-tests mean tests about tests? 
Yes. See

 Also, this is off topic but somewhat related: Is there also a
 panel-cointegration test available in gretl? 
No, not at present.
