I have designed this hands-on course to provide you an intense yet enjoyable instructional experience that focuses on a large number of both introductory and advanced topics in SEM using the latest version of one of the most well-known software package, IBM AMOS (Analysis of Moment Structures). In this course I will provide the materials and instruction that you need to both develop a good understanding of SEM and to be able to thoughtfully apply a variety of basic and advanced models to your data. More specifically, this course will cover a broad range of topics such as
• data preparation,
• model development,
• model fit assessment using various indexes,
• construct reliability and validity assessment using various methods,
• different methods to improve your model,
• structural model assessment,
• hypothesis testing,
• mediation using Baron and Kenny approach
• mediation using Sobel test
• mediation using bootstrapping method
• moderation,
• and multi-group analysis

very good dr sharif

Shall we use AMOS for a second order formative scale (with two reflective dimensions)?

[@saeedsharif]

If you have formative constructs, you may consider VB-SEM methods.

I want to study the relation between air pollution and economic growth . I have 3 latent variables and 10 observed variables. Yearly wise data from 1970 to 2015 is available for all my target variables. Now have a problem and confuse that I can not apply CB SEM . kindly guide me .either I can use CB SEM or not for that available size of data?

[@Alhamzah_F_Abbas]

Thank you so much. can we also use PLS for a large sample size?

[@saeedsharif]

Yes. You can use it for both small and large sample size

[@semagn2127]

Thank you!

Hi Prof, any ideal number for small and large sample sizes you mentioned?

[@saeedsharif]

Well, it depends. Generally, to be on the side of caution, it is recommended to have at least 300 to 500 samples for CB-SEM (covariance-based structural equation modeling). For VB-SEM (variance-based structural equation modeling), you can run the model with as few as 50 samples, although it may be challenging to convince others of its validity. This limited sample size restricts the generalizability of the findings. So, even for VB-SEM, it is advisable to strive for a sufficiently large sample size.

@@saeedsharif Thank you Prof for your reply. Appreciate it :)

@@adlinariffin1628 A pleasure! All the best!

Can we use CB SEM for 45 years data?
