1). Standard Deviation Index (SDI) = (Individual Result - Individual Mean) / Individual SD
2). Coefficient of Variation Ratio ( CVR ) = Individual CV /  Mean of all participating laboratories CVs
* Intermediate Measurement Precision¡FISO 3534-2:2006, JCGM 200:2012 ( VIM, 3rd ed. ) 2.23
** Mean and SD are calculated by Robust method according to ISO 13528, Algorithm A.
*** n < 5, not calculated Mean and SD.
