A study by researchers at Virginia Tech established a systematic framework for human expert evaluation of large language models in statistical SAS programming. Their evaluation of GPT-3.5, GPT-4.0, and Llama 3.1 70B across 207 tasks found that while LLMs generate syntactically plausible code, they scored significantly lower in executability (61.20%) and output correctness (51.69%) compared to code readability (94.05%).

Key insights

  • LLMs demonstrated strong capabilities in generating syntactically correct and readable statistical code, yet struggled significantly with code executability and producing accurate statistical outputs.
  • There was no statistically significant difference in overall performance among GPT-3.5, GPT-4.0, and Llama 3.1 70B across the evaluated statistical programming tasks.
  • The human evaluation process exhibited high consistency among expert raters, validating the reliability of the assessment methodology.
