Hello, I have a questions about common method biases. I have collected data using an online survey for latent constructs each measured on several items. However, I have also manifest categorical variables like gender (2 levels Males/Females) and education (2 levels High/low education) and single ite...

Hello, I need to test the significance of the increase in R2 of two nested models in SEM-PLS and I am using the following formula: F=((R2L-R2S)/(dfL-dfS))/((1-R2L)/(N-dfL-1)) where R2L is the R-squared of the endogenous variable from the model with more variables, and R2S is the R-squared of the pre...

Hello, I was wondering if any of you could help me with an issue to which I cannot find any answers online and/or in books. I need to carry out posthoc multiple comparisons between three groups after an OTG. However, I cannot use the permutation test as my sample sizes are quite different (respectiv...

Hello everyone, hope you can help me with this as I am stuck in my data analysis. I know I can obtain unstandardized latent variable scores from the IPMA. I also read online lots of articles discussing Hypothesis testing through the latent factor scores. My questions are: I need to carry out a t-tes...

Hello, Hope you are all well! I have a problem and I really hope you can help me. I would like to test if the difference in the R2 of two nested models is significant. For both models, I am using exactly the same data-set. In the second model, I just added an exogenous construct. Variables are not n...
