This is a great presentation by Chuck Huber on SEM and Stata. I'm a novice at both and have been struggling. This two hours was well worth the time investment. Thank you to USC for making this available online and thanks to Chuck for the wonderful presentation. // John in Singapore.
Hi Professor Huber. Excellent presentation! I am really impressed with what one can do with the GSEM function, particularly as it relates to multivariate multilevel modeling. My question is: Is it possible to use GSEM to estimate the covariances of the first level residuals (in a 2-level multivariate model) when both dependents are ordinal ....so that the the estimated variance of each of these residuals is pi squared on 3. The dependent variables (students' math and English grades) are correlated so that one would expect the first level residuals to be correlated. Schools represent the second level in the model.
Very informative! I would very much appreciate it if someone let me know how I can find the “cair.dta” that is used in this lecture? I’d like to exercise ;)
If I include only observed variables in simultaneous equations model (no latent variables), can I call it structural equation modelling or just pass analysis?
Hi Dr. chuker Huber; I am a PhD student at Flinders University, Australia and I want to be clear with one point. I tried to fit SEM to my data but I found a lot of exogenous and mediator variables that made my path diagram very complicated and I want to know if it is possible to fit first an ordinary model and use variables which are only significant in the final model for building my SEM. Or if there are any other options used to reduce these variables.
Hi , I have one dependent variables called ( IWFP billion m3 ) for 3 crops. and 4 independent variables ( RWr billion m3 year-1 + Ta Celsius + precipitation mm + productivity kg/ha for 3 crops) Yearly data for a country Observation 19 years I want to do the analysis and see the effect of independent variables, Please any suggestions, which is the perfect model I can apply and dealing with ?? , thank you in advance
Great presentation, thank you so much. However, the other people wearing a mic I suppose, not the presenter, laugh or sneeze/cough, whisper etc during the presentation and it is VERY irritating when you are wearing headphones to listen to the presentation. Others should not be wearing the mic throughout the presentation, but only when they had smth to say. When you are recording smth, only the presenter should be wearing a mic throughout the whole presentation.

Hats off for you, Sir, such a nice way of teaching a very complex subject and transformation into an easier way.
Great presentation with clear buildingblock and how-to-do skills
Great workshop, clearly presented practical knowledge.
Thanks a lot. Wonderful introduction to SEM. the best i have watched.
how does SEM take care of omitted variable bias? Also simultaneous bias such as, funding affects GPA but the GPA also affects funding?
What is the name of the textbook he suggested on minute 27:21, I barely understood what he said.

Great lecture sir! is it possible to have access to that big zip file, seems it is nolonger there ..

Thank you. A nice video.
Thank you! VERY helpful!!

Very helpful...than you so much
great video thank you so much
TQVM was useful, if have any video about Moderate &/or Mediate PLS shair it
Hi ,
I have one dependent variables called ( IWFP billion m3 ) for 3 crops.
and
4 independent variables ( RWr billion m3 year-1 + Ta Celsius +
precipitation mm + productivity kg/ha for 3 crops) Yearly data for a
country
Observation 19 years
I
want to do the analysis and see the effect of independent variables,
Please any suggestions, which is the perfect model I can apply and
dealing with ?? , thank you in advance
Thank you very much it is helpful
how can i do if my data is panel
make a 'panel data set' and input it on Stata.
also wanted to ask the same question
. .. Thank you very much
Thanks
great chuck... ok with @Ellen Almirol, sound a bit of an issue, but all good.
Great presentation. The guy who scoffs or laughs in the background is sort of annoying, but the speaker did very well on a very complicated matter.
