Structural Equation Modeling and AMOS – Evaluating the Explanatory Power of a Full Structural Model
This video explains the concept of a model’s explanatory power (EP) and how to evaluate it in AMOS. It is an optional step in Structural Equation Modeling (SEM) to evaluate how well the model explains the target variable (endogenous construct) based on input variables (exogenous constructs). Detailed steps for determining the EP measures, how to calculate them in AMOS, and how to interpret the outcome are provided with specific examples.

gracias!
Is there any way we can convert the column type in SAS miner? After importing the dataset my column is made Nominal as it has values "ZERO" for some rows. I used the replacement node to convert it to period. Now I want to convert the rep column to Interval type!
That was very helpful! Thank you so much.
Could you please explain the decisions you made for the properties on the impute node in score properties? Why did you choose indicator variables type Unique
Is there a version of enterprise miner for Mac? Or are you using some other OS?
There is no version of entreprise miner for mac you have to install a virtual machine to get it
Please can you make a reference of the name of the title of the book that you are referring in the video? Thanks
