Statistical Details for Measurement Systems Analysis

Intraclass Correlation without bias is computed as follows:

Intraclass Correlation with bias is computed as follows:

Intraclass Correlation with bias and interaction factors is computed as follows:

Probable Error is computed as follows:

Note the following:

= variance estimate for pure error

= variance estimate for product

= variance estimate for bias factors

= variance estimate for interaction factors

Z0.75 = the 75% quantile of standard normal distribution
