Statistical methods in process management — Capability and performance — Part 6: Process capability statistics for characteristics following a multivariate normal distribution
ISO 22514-6:2013 provides methods for calculating performance and capability statistics for process or product quantities where it is necessary or beneficial to consider a family of singular quantities in relation to each other. The methods provided here mostly are designed to describe quantities that follow a bivariate normal distribution. In principle, this part of ISO 22514 can be used for multivariate cases. ISO 22514-6:2013 does not offer an evaluation of the different provided methods with respect to different situations of possible application of each method. For the current state, the selection of one preferable method might be done following the users preferences. The purpose is to give definitions for different approaches of index calculation for performance and capability in the case of a multiple process or product quantity description.

Statistične metode za obvladovanje procesov - Sposobnost in delovanje - 6. del: Statistike procesne sposobnosti karakteristik, porazdeljenih po multivariatni normalni porazdelitvi
Ta del standarda ISO 22514 zagotavlja metode za izračunavanje statistik glede delovanja in sposobnosti za procesne ali proizvodne količine, kadar je potrebno ali koristno obravnavati družino posameznih količin v medsebojni povezavi. Tu navedene metode so namenjene predvsem opisu količin, porazdeljenih po bivariatni normalni porazdelitvi. Ta del standarda ISO 22514 ne omogoča ocene različnih zagotovljenih metod ob upoštevanju različnih razmer možne uporabe vsake metode. Za trenutno stanje se lahko izvede izbira ene prednostne metode v skladu z izbirami uporabnikov. Namen je navesti definicije za različne pristope izračuna indeksa za delovanje in sposobnosti v primeru opisa več procesnih ali proizvodnih količin.
