"psychonetrics"Main class for psychonetrics results.
Objects can be created by calls of the form new("psychonetrics", ...).
model:Object of class "character": the model framework (e.g. "varcov", "lvm", "var1").
submodel:Object of class "character": the submodel/type within the framework (e.g. "ggm").
parameters:Object of class "data.frame": the parameter table (one row per model parameter, with estimates, standard errors, matrix/row/col indices and parameter numbers).
matrices:Object of class "data.frame": bookkeeping table of the model matrices and their dimensions.
meanstructure:Object of class "logical": whether a mean structure is included in the model.
computed:Object of class "logical": whether the model has been estimated (run).
sample:Object of class "psychonetrics_samplestats": the sample statistics used in estimation.
modelmatrices:Object of class "list": the model-implied matrices in list form (per group).
log:Object of class "psychonetrics_log": the logbook of actions performed on the model.
optim:Object of class "list": the raw output of the optimizer.
fitmeasures:Object of class "list": computed fit measures.
baseline_saturated:Object of class "list": the baseline and saturated models used for fit computation.
equal:Object of class "character": names of matrices constrained equal across groups (legacy representation; the parameters table is authoritative).
objective:Object of class "numeric": the value of the fit function at the solution.
information:Object of class "matrix": the Fisher information matrix.
identification:Object of class "character": the identification method used (e.g. "loadings" or "variance").
optimizer:Object of class "character": the optimizer used.
optim.args:Object of class "list": arguments passed to the optimizer.
estimator:Object of class "character": the estimator used (e.g. "ML", "FIML").
distribution:Object of class "character": the assumed distribution (e.g. "Gaussian").
extramatrices:Object of class "list": additional helper matrices used internally.
rawts:Object of class "logical": whether raw time-series data are used.
Drawts:Object of class "list": duplication/derivative matrices for raw time-series estimation.
types:Object of class "list": the type of each model matrix per group.
cpp:Object of class "logical": whether the C++ backend is used.
verbose:Object of class "logical": whether progress messages are printed.
penalty:Object of class "list": the penalty configuration for penalized (PML/PFIML) estimation, holding the penalty strength (lambda) and elastic-net mixing parameter (alpha).
signature(object = "psychonetrics"): ...
signature(object = "psychonetrics"): ...
signature(object = "psychonetrics"): ...
signature(object = "psychonetrics"): The print output extended with the main fit measures (log-likelihood, number of parameters, AIC, BIC, RMSEA, CFI, TLI). Use fit for the complete list of fit measures.
