Figure 1 Graphical user interface for random data generation
Functions are implemented to generate data for a specific model (Figure 2). The true model considers three formative exogenous constructs and one formative endogenous construct. Linear effects are specified in a binary matrix as well as nonlinear and interaction effects. The interface allows one to set the number of data sets or Monte Carlo replications and the sample size of each data set; it is advisable to consider a sample size equal to or higher than 100 observations. All the measurement models have to have the same number of manifest variables. Four options can be used: 2, 4, 6, and 8 indicators per construct.
For each true model, two sets of true outer weights are available. The value of the outer effects may be equal in all measurement models or a set of different permissible values may be considered. Manifest variables are generated as random normal data.
