The Munich Procedure – Standardising linear regression documentation in p-XRF research

Abstract

The Munich Procedure, a protocol presented as R code and initially developed on the basis of archaeometric portable X-ray fluorescence (p-XRF) data, offers adaptability and standardisation to evaluate coefficient corrections. These corrections are derived from linear regressions calculated by comparing p-XRF values with laboratory chemical analyses of the same sample set. The versatility of this procedure allows collaboration and ensures consistent data structure. Not tied to specific instrumentation, this approach helps to universally improve the accuracy of p-XRF data, benefiting specialists in a variety of industries. By providing a common baseline for performance evaluation, it enables discussion across different applications.
