Question: Test de SHAPIRO WILKS - pvalue


I have a problem with the type of the pvalue in the Shapiro-Wilks test.

My program :

pv := ShapiroWilkWTest(Mat1, level = 0.05);
whattype(pv);  list  
eval(pv[2]);  "pvalue = 0.25..."  This result is an element of a list but not a real number

I would like to obtain the real value of pvalue in order to make a calulous with it.

I have tried as an example in Maple :

pv := ShapiroWilkWTest(Mat1, level = 0.05,output=pvalue); but it doesn't run.

May someone help me? Thank you very much
