Show Major Options in an Output of 'lavaan'
Description
Display the values of
major options in a model fitted
by lavaan::lavaan()
or its
wrappers (e.g., lavaan::sem()
or
lavaan::cfa()
).
Usage
show_options(fit)
## S3 method for class 'show_options'
print(x, ...)
Arguments
fit |
An output of
|
x |
The output of |
... |
Additional arguments. Ignored. |
Details
It extracts the values of
major options in the output of
lavaan::lavaan()
or its wrappers
(e.g., lavaan::sem()
or
lavaan::cfa()
.
It checks the actual values, not
the call used. This is useful for
understanding how a prepackaged
estimator such as ML
, MLM
, and
MLR
set other options. It
supports the following options:
Estimator (
estimator
)Standard error (
se
)Model chi-square test(s) (
test
)Missing data method (
missing
)Information matrix used for computing standard errors (
information
)Information matrix used for computing model chi-square (
information
)Whether the mean structure is included.
Value
A show_options
-class object with a
print method that formats the output.
Methods (by generic)
-
print(show_options)
: The print method of the output ofshow_options()
.
