A Latent Variable Model for Hybrid Data from Interlaboratory Comparisons

A new approach to estimate laboratory biases in interlaboratory comparisons is presented. Quantitative results as well as qualitative information from a survey (hybrid input data) are combined using a model that includes both a hierarchical regression model for biases and a structural nist-equation model for the answers to the survey. The complete model applies when some latent variables explain simultaneously the measurement results and the answers to the survey.
