This was a very helpful video. I am working with a dataset of nearly 2 million cases, so a correlation matrix is much easier to use than raw data! I was able to put your video to use and was running models in no time. Thank you!
Hi Sir, thank you very much for your video. I have a question: usually, to run a model in Amos, it is required to draw the constructs connected with observed variables (items used to measured that construct), otherwise i coundnt run it because Amos always shows a notification of erros relating to observed variable (when i only use the elip) or unobserved variable (when i only used the rectangle). But here in your video, i can see that you only use the rectangle to indicate the construct (instead of the elip) without any observed variables, and still it works. Could you please explain why and guide me how to do that! Thank you very much!
With AMOS, rectangles are used to show "observable" constructs. In this video, I summated all the survey questions for a construct into one value and then had that value denoted as the "observable". If you are going to use an "unobservable" constructs (circles), then you will need to attach observable variables to those unobservable constructs. If you have time, checkout my video for the different models of SEM. ruclips.net/video/U9bPwqBTMrw/видео.html That should really help to clarify the issue.
I am investigating the subject, could facilitate the applied questionnaire or say where article I can consult to strengthen my operationalization. Thank you!
