Internal: Classify structural model terms by type
Classify terms of the structural model according to their type.
classifyConstructs(.terms = args_default()$.terms)
.terms |
A vector of construct names to be classified. |
Classification is required to estimate nonlinear structural relationships. Currently the following terms are supported
Single, e.g., eta1
Quadratic, e.g., eta1.eta1
Cubic, e.g., eta1.eta1.eta1
Two-way interaction, e.g., eta1.eta2
Three-way interaction, e.g., eta1.eta2.eta3
Quadratic and two-way interaction, e.g., eta1.eta1.eta3
Note that exponential terms are modeled as "interactions with itself"
as in i.e., eta1^3 = eta1.eta1.eta1.
A named list of length equal to the number of terms provided containing a data frame with columns "Term_class", "Component", "Component_type", and "Component_freq".
