Extract a model definition that can be applied to lavaan::cfa for a confirmatory factor analysis
based on provided scales and items.
Usage
lavaan_model(scales, adds = "", orthogonal = FALSE)
Arguments
- scales
A list with scale information. Each element in the list corresponds to a scale
and contains a character vector with item names.
- adds
Additional model definitions as a character string.
- orthogonal
IF TRUE, covariance parameters are set for orthogonal latent factors.
Value
A character string with a lavaan model definition.
Details
Each scale in scales is defined as a latent factor, with items
as observed indicators.
If orthogonal = TRUE, covariance parameters between latent factors are set to zero.
Additional model definitions can be added via adds.
