用于拟合结构方程模型(SEM)的语法或代码传达了有关模型规范和估计SEM的方式的有价值的信息。我们从229篇使用LISREL、AMOS或Mplus运行SEM的随机抽样文章(发表于1998-2013年)中请求了SEM语法。在交换了500多封电子邮件后，我们最终只得到了这些文章中使用的57个句法(占我们要求的句法的24.9%)。结果考虑到回复我们请求的129名(对应)作者，自文章发表以来，句法丢失的几率每年增加21%，而实际获得句法的几率每年下降13%。因此，对于重复性和纠正中小企业运行和报告中的错误至关重要的扫描电子显微镜语法通常不可用，并且很快就会丢失。首选的解决方案是在文章旁边或数据存储库中强制共享SEM语法。
The syntax or codes used to fit Structural Equation Models (SEMs) convey valuable information on model specifications and the manner in which SEMs are estimated. We requested SEM syntaxes from a random sample of 229 articles (published in 1998-2013) that ran SEMs using LISREL, AMOS, or Mplus. After exchanging over 500 emails, we ended up obtaining a meagre 57 syntaxes used in these articles (24.9% of syntaxes we requested). Results considering the 129 (corresponding) authors who replied to our request showed that the odds of the syntax being lost increased by 21% per year passed since publication of the article, while the odds of actually obtaining a syntax dropped by 13% per year. So SEM syntaxes that are crucial for reproducibility and for correcting errors in the running and reporting of SEMs are often unavailable and get lost rapidly. The preferred solution is mandatory sharing of SEM syntaxes alongside articles or in data repositories.
