Re: unclear reviewer's comment on construct validity
Dear Irene, I am not fully sure however it really seems that the reviewer was irritated about your mentioned point. It is exactly as you assume that the correlations are based on the weighted factor scores in PLS. What is disturbing me a little bit is that the reviewer seems to expect that you shoul...

Re: unclear reviewer's comment on construct validity
Hi Irene, I would agree with the reviewer comment. However, I have often seen this mixing of EFA and PLS. Although, reputable researchers advise to avoid mixing results from an explorative factor analysis with a confirmatory factor analysis like PLS-SEM because of the problems of model over-fitting ...

By the way, I have an Excel template which you can use for testing the difference. That template is based on the corrected formula by Chin that you can find in my working paper on page 46 (in the orignal formula was a small bug): http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2097324 Best regards,

At the moment I do not know a source for PLS-SEM who exactly matches to your question. However, because regression analysis and PLS-SEM are very similar you can use e.g. following source which refer to a regression analyses: http://www.udel.edu/soc/faculty/parker/SOCI836_S08_files/Paternosteretal_CR...

Hi, You can use the same approach for testing the difference of two path connections in one single model as you us for path connections in different models. You can use Chin’s test or Henseler’s group test or simple the difference of the bootstrap distribution in an Excel template. Greetings, Christ...

Hi Katja, With help of the bootstraps results from a PLS-SEM program you can easily calculate the CI via assistance of a spread-sheet application, such as Microsoft Excel. That means the results table of the bootstrap subsamples needs to be copied and pasted into a spreadsheet application. To produc...

Hi Katja, For a sample size greater than 30 observations the normal critical values can be used determining the significance levels. Thus, if the t-value is above 1.96, you can assume that the path coefficient is significantly different from zero at a significance level of 5% (error term = 0.05; two...

Hi, at question a) In the actual SmartPLS version it is not possible using a dichotomous variable as dependent variable. For that case you need a logistic-regression. Therefore in your case a valid interpretation of you model is not promising. at question b) As your question indicates, the question ...

In general with help of SmartPLS it is possible to use “single” dummy variable as independent variables. But as far as I know you cannot use more than one dummy variable per construct with the actual implemented algorithms. Furthermore you cannot use a dummy variable as dependent variable. In the la...

I believe the review refer to the point that PLS as a SEM cannot say something about casual relation. Therefore you need always a good theory or some experimental studies for deriving a model in SEM. Perhaps you can check for your independent variables the VIF (variance influence factor) with help o...

You right, we really need better procedures. But “at least” you need the “same” indicators for the measurement when using a multigroup analyses. In the next step we have to check if the “loadings” are significantly different with such a test you mentioned e.g. “parameter free” test. Greetings, Chris...
