本文报道了由Bouchard和McGue(1981)回顾的对世界S智商数据的协方差结构的模型拟合分析。所使用的模型包括加性和非加性遗传参数，以及允许对不同类型的亲属进行不同估计的共享和非共享环境参数。我们借此机会解释LISREL在这方面的用法。结果表明，当模型中包含分类交配时，非加性和加性遗传方差对智商有重要影响。广义遗传力估计为0.51。另一个有趣的结果是，对于不同类型的亲属：双胞胎兄弟姐妹父母和他们的后代堂兄弟姐妹，共享环境的影响存在合理的差异。
This article reports a model-fitting analysis of the covariance structure of the world''s IQ data as reviewed by Bouchard and McGue (1981). A model is used which includes additive and nonadditive genetic parameters, and shared and nonshared environment parameters that permit different estimates for different types of relatives. The opportunity is taken here to explicate the use of LISREL for such purposes. The results indicate that, when assortative mating is included in the model, nonadditive, as well as additive genetic variance, is important for IQ. Broad heritability is estimated to be .51. Another interesting result is that the influence of shared environment differs in a reasonable way for different types of relatives: twins > siblings > parents and their offspring > cousins.
