the best video series of SEM and AMOS ever!

[benettaliu]

Hello sir, I've been following your videos for more than a year to learn AMOS. I deeply appreciate them! I have recently encountered something that baffles me. When I do a path analysis in AMOS, the direct effect between A and B is nonsignificant (in "estimates", the p-value of "A --> B" is larger than .05). However, when I do linear regression in SPSS with A being the independent and B being the dependent, the result is significant (p < .05). And this happened to several other pairs of variables in my path. How could this happen? Which one is correct? Thank you in advance for your help!

When is it advisable to include or remove the intercepts from the model specification. I am using JMP SEM fit. The most obvious effects of not including the intercepts is much higher R2, loss of some indirect effects (which would really make the results easier to interpret), and too many deep red squares (which do not show when intercepts are included) in the normalized heat unit map. Your advice would be greatly appreciated. There are obvious tradeoffs.

Just amazing and specific. I like your tutorials. Mike, can you teach us Mplus path analysis? I need your suggestion

Thanks teacher. It is very important and useful.😊😊😊

[MrDevid]

Thank you Mike for your detailed explanation with example.

Thanks Mike Crowson, very informative video. I just want to ask that if I understand correctly, Model Fit is not necessary when doing a mediation analysis in SEM, right?

[botaefemerave]

I have a moderates Mediation like process number 10 But with 3 moderators. Problem is my Model is identified But Not over identified, so i dont get results on the Model fit. What can I do?

[makmursujarwo]

Hello sir, for the mediation value in the bootstrap P-value = 0.021.
Lower bound=0.351
Upper bound=1.251.
Is this significant or not?

[justinslater]

Absolutely helpful. A great video for answering many of my questions from reading Kline 2016.

Hi Mike Crowson, great video. Question: Direct & Indirect effects are like the "spillover effect"? Thanks

[immanuelshittu]

what is the easiest way to identify an exogenous variable in path analysis?
Because sometimes, l look confuse in identifying the right variable for exogenous in path analysis.

If modification indices suggest direct effects of both variable A predicted variable B, and variable B predicting variable A...how would you do revise the model? Do you allow for correlation (i.e. double headded arrow)? Or would this suggest adding a latent variable?

Thanks Mike for the amazing video. I have questions regarding the chi2 value that you got there. your chi1 value is 4.415 and p value is 0.036 which means that your model is differ significantly from the saturated/just identified model. Do you think that this can be a problem? If I am correct, it means that the structure that we make is not "correct". I see others also said that the model is acceptable if the p value is above 0.05. Could you give some insights please? thanks.

Hello, thanks for the video. Please, can I know what is the name of this method?

[godd]

Great tutorial. Can anyone help me with how to write the model M1 and M2 at 1:52 in a form of an equation?

[hanakim]

Hi, Mike, thank you very much for your video. I have a little question about evaluating indirect effect using Amos, that how to compare the significant differences between two indirect effect in different condition using Amos, my reviewer told me to use nest-model comparison approach, but I'm not sure how to conduct it in Amos. I would be much appreciated if you can answer my question. thanks again.

[PRATIKGHOSH]

Hello, is it possible to have insignificant direct and indirect effects but significant total effects? what does it mean?

[هبهالبدوى-جض]

Thanks Mike for your amazing videos.
Please, I need your help. My model is a latent model. i follow the steps you used here in this video to test mediation relationship in my model. what I should write in my paper about this method (what is its name)? Also, is there any reference I can cite for this method?

[KT-zknm]

Hey, why does the number of distinct sample moment differ?
