Hi Expert,
I read your post regarding the calculation of the communalities, AVE for second order factor (with reflective 1st order construct). However, I have some question about it. Does it apply to Reflective-Reflective construct?

Hi,
if we have the LV_2nd with 3 reflective LV_1st, with these loadings:
LV1 ==> 0.6
LV2 ==> 0.7
LV3 ==> 0.8
The communalities will be:
LV1 ==> 0.6^2 = 0.36 = 36% (variance of the LV1 explained by the LV_2nd)
LV2 ==> 0.7^2 = 0.49 = 49%
LV3 ==> 0.8^2 = 0.64 = 64%
The AVE will be: (0.36+0.49+0.64)/3 = 0.49666 = 40.6%
end of quote.
I am a bit confused. What exactly do you mean by loadings? Because as in my case, I have a Type 1 construct (reflective-reflective), when I developed the final model with all the constructs (5 reflective exogenous contruct, one Reflective-Reflective endogenous/exogenous construct, three reflective endogenous constructs). I only have the outer loadings for MVs for each construct. Does it mean to calculate LV-2nd AVE and commualities, I will need to use that outer loadings? But there will be more than one loading from each LV-1st. Please advise what to do?
Thanks!
Communalities, AVE for 2nd order construct

Hi,
It is simplier:
- the relations between 2nd order LV and their 1st order LV are "measurement", for this reason, these relations should be interpreted as "outer loadings" or "factor loadings".
- but the report of SmartPLS (and others softwares) will include these relations in the path coefficient report.
Best regards,
Bido

Thanks. I understand that the "outer loading" or "factor loading" can be found in the PLS algorithm report. So to confirm my understanding, in order to calculate the AVE n communality for my LV-2nd, I will use these loadings? But I also noticed that these values are included in the PLS algorithm report together with the values for the LV-1st, does it mean that I still have to calculate these values or simply use those in the report?
Thanks!
Thanks!
