Theoretical doubts about PCE UQLAB

Dear all, good afternoon. I hope you are doing well. I am from Brazil, a master’s student in engineering. I am building a metamodel and have one more question. Are the “mean value” data in the output of PCE relative to yo in equation 1.37 of the “UQLAB USER MANUAL POLYNOMIAL CHAOS EXPANSIONS”?

Dear @Juliana_Maia

Yes, the mean, standard deviation, and coefficient of variation are the analytical values derived from the PCE coefficients.

Best regards
