In our latest research, led by Sadie Barlow and with Dr Edoardo Manino, we discovered a very important property of LambdaG: it does not require a calibration dataset to produce well calibrated likelihood ratios. A simple correction is sufficient. This means that the analysis is significantly simpler to implement and explain. LambdaG is therefore also the only existing authorship verification method that does not require a calibration analysis to produce likelihood ratios.
The paper, currently under review, is available on arXiv here: https://arxiv.org/abs/2607.09501.
