您好!, t: g3 F9 r4 N6 a, X
首先非常感谢您在中人网上给我非常详细的解答,我感觉受益匪浅!
! j. u0 Y' J" s 但是同时也让我陷入了矛盾之中,如果按照我的模型修正方法,把同一构念的两个观测指标的测量误差相关,整体模型的拟合度将会显著提高,而且研究的关键路径 也会显著!如果不这样做,可能这篇paper就要废掉了,我有点矛盾!我见过别人这样调整模型,但是在正文中没有报告出来,模型 的拟合度很高,也发在了级别很高的期刊上!' W( i% z" v2 T2 H9 E, ^
谢谢,祝您一切顺利! C5 b5 A. U' ]! Q% I7 Y

Hi Tony,
! H* d; {! v& }: q/ `: V
T# m% |8 B; d, s8 fWhat don't you reply on the blog? I would hope that we can carry on with the discussion there so that everyone can learn together.
9 [6 h# j5 w' W1. How do you know they do so if they do not report?
, A( I, [: u8 D2 \0 s2. If there is nothing wrong with it, why don't you report?
) W% U/ _/ B5 X% u3. If you know that you cannot report (otherwise you would be challenged), therefore, you keep silent about it. Is this academic dishonest?
/ H# @& a$ M; Y" b4. If your fit would increase significantly simply be correlating ONE measurement item, that means it is the measurement model which causes the problem, not your structural model. I would suggest two approaches to you:
7 \0 A% J9 ^2 M1 |! i(a) use item parceling to group the two correlated items;
) R3 J: M" M/ a8 [ p2 C5 p0 r% ^(b) first run a CFA, then average the items for each construct and run a path analysis (no measurement model).# i' P) \4 P2 _1 J# v. [3 C; z
