Setting Statistical Hurdles for Publishing in Accounting
ACCOUNTING ECONOMICS AND LAW-A CONVIVIUM（2023）
UCLA Anderson Sch Management
Abstract
Ohlson (2023) argues that researchers tacitly avoid raising statistics-related ‘elephants’ that could undermine inferences. We offer a balanced perspective, first applauding the remarkable progress made in deriving testable predictions, leveraging modern statistical techniques, and tapping alternative Big Data sources to address issues relevant to practitioners, regulators and academia. While we concur with Ohlson’s elephants, we caution against over-criticism based on statistical design choices, as it risks creating new elephants. Our key lessons: focus on meaningful hypotheses, recognize merits of descriptive studies, balance Type I and II errors in data handling and journal reviewing, employ proper context when interpreting statistical significance and consider economic significance. Overall, though empirical accounting research faces challenges, criticism should not deter innovative research (Type II error in journal reviewing).

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
