internal function. Translates an object of class lavaan to the internal model representation.
Usage
.SEMFromLavaan(
lavaanModel,
whichPars = "est",
fit = TRUE,
addMeans = TRUE,
activeSet = NULL,
dataSet = NULL,
transformations = NULL,
transformationList = list(),
transformationGradientStepSize = 1e-06
)Arguments
- lavaanModel
model of class lavaan
- whichPars
which parameters should be used to initialize the model. If set to "est", the parameters will be set to the estimated parameters of the lavaan model. If set to "start", the starting values of lavaan will be used. The latter can be useful if parameters are to be optimized afterwards as setting the parameters to "est" may result in the model getting stuck in a local minimum.
- fit
should the model be fitted and compared to the lavaanModel?
- addMeans
If lavaanModel has meanstructure = FALSE, addMeans = TRUE will add a mean structure. FALSE will set the means of the observed variables to the average
- activeSet
Option to only use a subset of the individuals in the data set. Logical vector of length N indicating which subjects should remain in the sample.
- dataSet
optional: Pass an alternative data set to lessSEM:::.SEMFromLavaan which will replace the original data set in lavaanModel.
- transformationGradientStepSize
step size used to compute the gradients of the transformations
