讨论了如何目前的拟合优度指数无法评估简约性，因此不可证实的模型，是不敏感的误指定的因果关系（a）之间的潜在变量的测量模型时，许多指标是正确的和（B）当因果关系对应的自由参数预计将是非零变成零或接近零。讨论简约的哲学阐明了简约的关系，参数估计，不确定性，拟合优度。LISREL中的AGFI被拒绝。提出了一种用简约比调整拟合优度指标的方法。讨论了结构模型（不含测量模型）拟合优度的小偏差估计和检验拟合的相对正态拟合指数。
Discusses how current goodness-of-fit indices fail to assess parsimony and hence disconfirmability of a model and are insensitive to misspecifications of causal relations (a) among latent variables when measurement model with many indicators is correct and (b) when causal relations corresponding to free parameters expected to be nonzero turn out to be zero or near zero. A discussion of philosophy of parsimony elucidates relations of parsimony to parameter estimation, disconfirmability, and goodness of fit. AGFI in LISREL is rejected. A method of adjusting goodness-of-fit indices by a parsimony ratio is described. Also discusses less biased estimates of goodness of fit and a relative normedfit index for testing fit of structural model exclusive of the measurement model.
