title: Supplementary Material - Who Should Test the Requirement? A Comparative Study on Requirements Classification for Assigning Test Teams using the Pre-Trained Models

description: The supplementary material is related to the statistical tests performed to validate the results from the paper "Who Should Test the Requirement? A Comparative Study on Requirements Classification for Assigning Test Teams using the Pre-Trained Models"

The goal of the statistical test was to investigate whether there is a significant difference between the BERT, XLNet, and ELECTRA models with regard to the probability assigned to the correct class of each requirement. For the statistical test, we used a set of probability distribution to the model classify correctly each class:
