Dear Hengkov,
Thank you so much. I would be extremely thankful for if any specific reference. and second:

Is Predictive relevance (Q^2) is applicable to second-order construct (with reflective dimensions).

SmartPLS does not provide it so you have to calculate it manually.

### R^2 and Q^2

Why my R^2 and Q^2 values exactly same? (I used second-order construct with reflective dimensions)

The final endogenous variable will be your final R^2. Use the following assessment of structure model (Hair et al., 2013. A primer on PLS-SEM - Book) 1. Check collinearity among the constructs 2. Bootstrapping to assess the significance of the path coefficient 3. R^2 4. Effect size (f^2) 5. Predicti...

### Re: R square values

Hi, Go to Calculate=> Run PLS Algorithm then you can see your model (endogenous variables only). Also after running PLS Algorithm go to the Report=> Default Report => Overview here you can see R^2. You don’t need to calculate by hand. Assessment of structure model (Hair et al., 2013. A primer on PLS...

### Re: How to interpret Total Effects?

Hi,
The others are the indirect effects which can be calculated as the product of the two effects . for example
Direct path of AB=0.2
Indirect path AC*CB => 0.8*0.5=0.4
Total effect=AB+( AC*CB)= 0.2+0.4=0.6

### Re: Single Indicator Reflective/Formative LV

According to Hair et al., (2013). A primer on PLS-SEM - Book), in case of two stage approaches, they mentioned that LVs measured with only one indicator are set equal to this indicator, no matter which measurement model setup is chosen (single-item constructs; pp.264-265). So I think, in case of sin...

### Re: GoF values for formative constructs

Hi,
Yes you are right.

Assessment of structure model (Hair et al., 2013. A primer on PLS-SEM - Book)
1. Check collinearity among the constructs
2. Bootstrapping to assess the significance of the path coefficient
3. R^2
4. Effect size (f^2)
5. Predictive relevance (q^2)
6. Do not use Gof

### Re: Formative measurement model assessment

Hi, Right now I am reading the exactly the same chapter. I was thinking what if take the average means of all formative indicators and make it as global single-item? How can I decide my global single-item measure as I have almost in the last stage of analysis. I did not finish the book now so am not...
