Discriminant validity is measured by comparing the square root average variance extracted with the inter factor correlations among factors. The sqr AVE of each factor should be larger than any of its correlations with the other factors (Fornell & Larcker, 1981).

Hi Mahmood,

For the methodology you may check Fornell & Larcker (1981) Evaluating structural equation models with unobservable variables and measurement error, journal of marketing research, 18, p39-50.

You will find the correlations and AVE in the standard report.

Good luck,
Dennis

Hi Mrs Tourky,

It is advisable to run the complete model instead of two algorithms. In this case all relevant relations you anticipate are weighed. In your thesis you may report that you tested the complete model so that all relations are weighed.

Good luck,

Hi Anastasios, Your first problem: In your model (figure) items are included for dimensions X and Y and for variables V3 through V6. Independent variable V2 and dependent variable V1 are not measured separately by items. SEM would require your model to include items construing independent variable V...

Hi Amanda, I interpret your model to be as follows: Advertising -> Awareness Advertising -> Knowledge Awareness -> Knowledge Knowledge -> Usage As a result awareness would be mediating the relationship Advertising -> Knowledge. You may check the following literature on mediation: Baron (1986) The mo...

Hi seusxl,

Based on your brief question, I interpret that Java is not intstalled on your machine. You'll need to install Java (version 6) and you may find it here: http://www.oracle.com/technetwork/java/ ... index.html
Look for “Java SE 6 Update 29”

Good luck,
Dennis

Hi Lama, Checking for mediation in SmartPLS is more straightforward than in SPSS and SAS. How to do it: (1) Create all relationships between independent variables (IV) and dependent variables (DV) according to your model (2) Create the mediating variables (MV) (3) Create the mediating relationships ...

At last found an interesting paper that deals with this issue: Wetzels, M., Odekerken-Schröder, G., & Van Oppen, C. (2009). Using PLS path modeling for assessing hierarchical construct models: guidelines and empirical illustration. Management Information Systems Quarterly, 33(1), 177-195. The pa...

Hi Kinda,
These options are very handy. The "Model export" option creates a backup of your workspace (data and models) that you're using. You may send this to a colleague or keep it as a backup. With "Model import" you may return to your saved workspaces.
Best regards

Hello Bido,

Thank you. XLSTAT-PLSPM looks an interesting program.

I also found interesting info in this thread: viewtopic.php?t=1094
