As a professor myself, I truly appreciate the way Prof. Sturgis present the course - focusing on intuition rather than mathematics, which in my view is of great importance for non-statistical students.
i like the way you explain things slowly and at ease. for someone unfamiliar with statistical analysis at all it's been helpful in understanding SEM. Great job Professor
This guy is a great speaker and very articulate. Thank you, Professor Sturgis. You took a very complicated topic and made it simple by breaking it down in three separate videos.
I’ve watched your videos over and over, each time my SEM understanding increases .. this time around the AHA moment occurred within the Mean Structure discussion , specifically reflexive vs formative indicators when measuring constructs like social capital and imposter syndrome.
That's great, very appreciative. Small note: at minute 18 there are only 5 single-headed arrows going from the latent variables to the indicators, not 6.
Great lecture. Thank you! Just noticed, on the first slide "Two Factor, Six Item EFA" there is an one-headed-arrow missing between eta2 and x3. But anyway, great lecture!
Could someone explain what is the definition of degrees of freedom here? Naively, I thought degrees of freedom are free model parameters, but this is in contradictory to the use of the term in the lecture. If we apply constraints, the number of free parameters decreases and hence the model becomes less flexible (less capable). How do I understand the fact that the less flexibility implies the larger number of degrees of freedom?
Thanks prof. I suggest to give numerical example and clarify each step. Only theory would not be understandable for everyone. Thus if could prepare a numerical example to explain the steps friendly.
Thank you Prof, it is informative and came in hand for my research. I have a question regarding the high order factors structure. Why is that the errrors are no longer respective to their observed indicators? such that error 3 points to indicator 1 etc?
Prof Patrick Sturgis - could you please confirm apart from psychology can SEM be used in other domain e.g. econometrics , finance , sentiment analysis ?
Hi! Thank you for this great explanation of the CFA. I wanted to ask what is the difference between item parcelling and the higher order factor model? Is item parceling a special case of higher order factor model?
Sir, my topic is to measure impact of work-life balance on job satisfaction. I measured these two through different constructs.Items were taken from existing questionnaires of different authors. I combined few constructs and I added and deleted some items form constructs. What should I use CFA or EFA and why. Sir, please guide
Thank you for great lectures! How do I calculate apriori sample size for CFA - I have seven 1st order and one 2nd order latent variables. Observable items 120 questions predominantly Likert type. Could you please assist?
Can our observed exogenous and endogenous variables be continuous and categorical (dichotomous,ordinal, binary) simultaneoulsy, if yes which software is most appropriate for conducting CFA and SEM then alongside moderation and mediation analyses.
Perhaps it is just me, but I find it very hard to fully grasp the material without worked examples. Some code or pseudo-code that made the procedures more precise would have been very useful. Everyone has their own learning style, but the one used here does not work for me.
Get a life! If you are so bothered by the eh's then don't watch! Better yet, if you're so damn great, make your own video! I watch the video to learn about SEM, NOT to worry about speech patterns.

I enjoy the way the Professor explains SEM so that even beginners can understand. Great job, Professor.

As a stats instructor myself I am very impressed by the clarity and concision of your presentation. Great job!
The best learning resource I’ve found so far. On point. Clear. Your style calms any anxiety
This guy is a great speaker and very articulate. Thank you, Professor Sturgis. You took a very complicated topic and made it simple by breaking it down in three separate videos.
he's a very bad speaker loads of ehs, for instance and it's way too slow to stay interested
The explanations here are simple yet insightful. A great job Professor!
Respected professor,
Thank you so much for providing more insights on SEM and many of the researchers will get benefited from your teachings.
I’ve watched your videos over and over, each time my SEM understanding increases .. this time around the AHA moment occurred within the Mean Structure discussion , specifically reflexive vs formative indicators when measuring constructs like social capital and imposter syndrome.
Been watching these videos to help me with my master's thesis and it has been a great help. Thank you!
Fantastic 3 lectures. Brilliant. Thank you for sharing, Kevin
Thank you so much for your concise and clear explaination of SEM in such a slow and elegant way! Gorgeous!
I really enjoy alot listening to professor Patrick sessions on SEM
IAM really impressed by the clarity and concision of your presentation. Great job prof !
I need to like this video twice. What a great explanation!
Me too
Seriously saving me right now :) Can't thank you enough!
Nice work Professor, I like your style of teaching. May God Lord Protect you
Enjoyed all three talks. Very well made. Thank you
Thank you so much Professor, it has been so insightful and helpful learning from you!
amazing lectures! Thank you very much indeed
Thank you so much for this ! Very clear and concise !
That's great, very appreciative.
Small note: at minute 18 there are only 5 single-headed arrows going from the latent variables to the indicators, not 6.
That's only for n2, not n1. I guess that is just an unintentional mistake.
Great lecture. Thank you! Just noticed, on the first slide "Two Factor, Six Item EFA" there is an one-headed-arrow missing between eta2 and x3. But anyway, great lecture!
sir add a line from n2 to x3 @ 18:32.......Your explanation is really v good, easy to understand

thanks Prof on the lecture ! really helpful may God Bless you
Better than I've learnt from school
Great series, thank you!

Thank you for such a nice lecture :)
Hi Dr., how if discriminant validity is NOT met after CFA? But model fit and convergent validity is met. What should we do? Can I do EFA?
Thank you so much, very very helpful!!! Please keep making video ...

Thank you! finally I could understand SEM!
Great lecture Prof. you make it very simple to understand. How can i analyse path analysis with categorical data?
This is an awesome lecture. Thank you

thank you,very clear explanation
Hi professor
Can we use 5 levels scale as bellows:
-2 -1 0 1 2
for EFA, CFA, SEM analysis?
dear professor if you can please show how to calculate sample size in structural equation model !!!
Thank you for great lectures!
How do I calculate apriori sample size for CFA - I have seven 1st order and one 2nd order latent variables. Observable items 120 questions predominantly Likert type. Could you please assist?
please prof what is NNI in one factor CFA ?
thank you for these very informative lectures
Remarkably crafted presentation and contents ...Great learning experience...Thank you. ..
I also enjoyed and understood well, but I am really craving an actual example
Without an apt example...all this has no real flavour
i like your explanation #CFA
I still don't see why it is required that students have to do SEM thesis, or a thesis at least
Brilliant lecture
Great information, thanks.
Can our observed exogenous and endogenous variables be continuous and categorical (dichotomous,ordinal, binary) simultaneoulsy, if yes which software is most appropriate for conducting CFA and SEM then alongside moderation and mediation analyses.
It can be done in AMOS
Thanks very much for the insight

thank you for ruining a very, very helpful video. Be better. Fuck you
