To test the fit of alternative models, the meta-analytically pooled correlation matrix was used to estimate path models using LISREL 8 (Jöreskog, & Sörbom, 1993). As each entry of a correlation coefficient was based on a different set of studies and thus on different sample sizes, the sample size for each entry varied substantially. As expected, this analysis revealed that the number of studies decreased with the number of rounds of data collection. The harmonic mean of the sample size (Viswesvaran & Ones, 1995) was computed to test the fit of alternative models to the data.

想了半天

原來有很多不同的方法可以處理sample size的問題

我想的太嚴格了

如果所有的paper都必須是fit X-M-Y才納入

那大概沒有幾篇可以玩吧~~~

 

不過保險起見

在資料許可的情況下

倒是可以針對 X-M-Y vs. (X-M, M-Y)兩類的資料做一個seneitive analysis (如果不一樣那就有尷尬了~~~)
