[Knowledge Sharing] SEM and Process Part I
最近又被詢問了 SEM and/or PROCESS 軟體使用時機, 說明一下:
PROCESS軟體已經廣泛用於行銷,心理...領域。
PROCESS軟體作者 Andrew F. Hayes多次說明,PROCESS 軟體使用時機。 Hayes et al. (2017)大作中再次強調:
1.SEM and PROCESS are based on different estimation methods and theory, some differences can be expected.
2.PROCESS is a computational tool — a “macro”—available for SPSS and SAS that simplifies the implementation of mediation, moderation, and conditional process analysis with observed(i.e., “manifest”) variables.
3....
4....
PROCESS不適用在latent variable model,因為無法估計。
混用 SEM+ PROCESS 需要解釋為什麼? 而不是想用就用,畢竟2種方法有其不同的estimation methods and theory,要求也不一樣。 不然,估計出來的結果是不精確的,如何解釋和下結論。 這是一篇Journal Paper被拒絕的部分關鍵。
