Re: SmartPLS basics

This would be a quite unusual practice, but you may also have good theoretical arguments. If a question does not fit to the other questions, you might see such behavior. If you can now argue that the questions (theoretically) also is the one that fits the least to the construct (based on your constr...

Re: PLS-MGA p-value result missing

My first guess would be that you have the "hide zeros" option on so that all zeros are not shown. This option is quite useful for some results, but not for all.

Re: Simple mediator effect

No. That would not be correct. There exists a formula to calculate standard errors for mediation using Sobels formulas. However, Sobel is not recommended anymore because it is less accurate and robust in many situations. Thus, bootstrapping the indirect effect is the preferred choice nowadays.

Re: Significance values of Path coefficients

You have to use the bootstrapping algorithm.

Re: Single indicator for each latent variable

We cannot provide individual counselling on how to build an appropriate model. We can only answer general methodological questions that might also be interesting for other researchers. If you need more input on your specific model, you may either purchase the enterprise license which comes with 8 ho...

Re: 4-point scale in questionnaire for analysis in SmartPLS

PLS algorithms use normal (Pearson) correlations and regression. Thus, they assume metric or at least quasi-metric data. Most researchers assume quasi-metric data for their questionnaire responses if it has sufficient categories (usually at least 5 or better 7 or more) and has equidistant categories...

Re: Reporting 95% CI

If you want to report the bias-corrected and accelerated bootstrapping confidence intervals you should report the values under "Confidence Intervals Bias Corrected" otherwise they will not be bias-corrected and accelerated, but normal percentile intervals.

Re: Outer loadings >1 in a CFA

Are you running a PLS model or a LISREL/AMOS/MPLUS analysis?

Re: singular matrix problem

There likely will be a problem somewhere with your model or data set. You could send the project (including the data set and model) to our support team and they might have a look at it.

Re: Single indicator for each latent variable

If you have no measurement model (only single indicators) there is nothing to calculate and the assumption for single indicators is perfect reliability (i.e., the construct is the same as the indicator). So this is ok. However, the question is, whether using only single indicator constructs is in ge...

Re: GDP as a country-specific control variable

You can include control variables as single-item constructs into your PLS model.

Re: PLS FAC-SEM

As far as I remember, FAC-SEM are procedural guidelines on how to combine different PLS results to analyze factorial SEMs. There is no specific algorithm for this in SmartPLS.

Re: Interpreting effect size F squared and Q squared

First, thresholds are never right or wrong. They are always arbitrary and to some degree based on the opinions of the authors or common practice in the field. The thresholds in the course slides that you show are based on the PLS Primer book 2nd edition. However, we do not use this slide anymore in ...

Re: Data Metrics - How to Standardise Raw Data - Using SmartPLS3

You do not need to standardize the data prior to importing it. SmartPLS will always standardize the data in the algorithm. In fact, it is usually better to import the unstandardized raw data, because standardization might be different if you analyse groups, have missing values, etc. In these cases i...
