Basic concepts of PLS-SEM?

Understanding the basic concepts of structural equation modeling is essential before researchers use SEM-based software for analyses. Whether one has a good background in statistics or mathematics, it is preferable as a researcher to grasp some fundamentals. I will probably devote more writing time to structural equations in the future…;) an article…..(a promise is a debt, the article is available, UPDATE – May 17, 2023)

What is the correlation coefficient?

These are the bivariate correlations between a construct and the indicators. They determine the absolute contribution of an element to its Latent Variable. Correlation coefficients are of primary interest in the evaluation of reflective measurement models, but are also interpreted when formative measures are involved. They are also called external loadings. The recommended value is 0.70.

What is indicator reliability?

Indicator reliability is the square of the correlation coefficient of a standardized indicator. It represents the portion of the variation of an indicator explained by the construct and is called the variance extracted from the item. Correlation coefficients greater than 0.708 are recommended, as they indicate that the construct explains more than 50% of the variance of the indicator, thus providing acceptable reliability of the indicator.

The Beta coefficient?

Are directional coefficients estimated in the structural model (i.e. between constructs in the model). They correspond to standardized Betas in a regression analysis.
