LNE Uncertainty: A user-friendly software for a validated implementation of the Guide to the Expression of Uncertainty in Measurement

LNE Uncertainty allows for the evaluation of measurement uncertainties by propagating variances or distributions in accordance with the GUM and GUM Supplement 1. LNE Uncertainty is capable of handling multiple output quantities, perform sensitivity analysis and goodness of fit tests. The software has been developed following the recommendations of European Metrology Network for Mathematics and Statistics (Mathmet) to ensure reliability. The software, a standalone application, is freely available. Its user-friendly interface, guiding through the evaluation process, democratises access to statistical methods, requiring no programming skills, yet demanding experience in the measurement uncertainty evaluation process.
