Hi, Used four step. Baron and Kenny (1986), Judd and Kenny (1981), and James and Brett (1984) discussed four steps in establishing mediation: Regards, The work of Hayes is also good with his website. PLS is superior to Sobel test for testing mediation as you can take advantage of bootstrapping capa...

Hi, If HOCs are formative, it does not make sense compute AVE and composite reliability. We do not expect that their LOCs will be correlated, for this reason they are used as formative. If HOCs were reflective, we should compute their AVE and CC based on their relations with LOCs (they are presente...

Why not do a power analysis instead given your small sample size.

that would be more useful

Hi, This is problem in formula GoF Absolute. If you leave single items construct out, the result will low and not explain models. Contrary, if you enter single items construct, the result will high and misleading. So, for alternative, you must compute GoF Relative. Regards, Hi, The PLS literature h...

Hi That's how we implemented things using an auto function. If you would like to create moderating effects differently, manually create the interaction term, import the dataset with the additional indicators and run the analysis A nice SPSS add in by James Jaccard called Zumastat is worth looking a...

Re: Compare alternative models

compare alternative models in smartPLS? Models should be driven by theory BUT it depends on the dominant research approach you are dictating up front. Joreskog and sorbom in early works in LISREL. state: strictly confirmatory, alternative models and model generating approaches are ways to apply SEM...

Re: 2nd order constructs type IV (formative-formative)

- 1st order constructs (now, in my eyes the interesting step) (a) If I take all 1st order indicators together and drop them on the 2nd order construct and model them formativ, i.e. all arrows point from the indicators to the 2nd order construct, I get really messy results. (b) If I model the "indic...

Re: Literature on empirical work with 2:nd order latent vari

Hi I wonder, - is there any good articles on empirical work that has modelled using second-order hierarchical latent variables, with the "repeated indicators approach" (Hair et al 2013 page 230), I would like to see how it works in reality.. Mattias Svahn See Wilson and Henseler work ANZMAC paper. ...
