This function reads EQS output files (.ets, .CBK and .ETP) into R and stores the results as objects.
Usage
read.eqs(file)
Value
Returns a list with the following objects:
model.info
General model information
pval
p-values for various test statistics
fit.indices
Variuos fit indices
model.desc
Descriptive measures
Phi
Phi matrix
Gamma
Gamma matrix
Beta
Beta matrix
par.table
Parameter table (with standard errors)
sample.cov
Sample covariance matrix
sigma.hat
Model covariance matrix
inv.infmat
Inverse information matrix
rinv.infmat
Robust inverse information matrix
cinv.infmat
Corrected inverse information matrix
derivatives
First derivatives
moment4
Matrix with 4th moments
ssolution
Standardized elements
Rsquared
R-squared measures
fac.means
Factor means
var.desc
Descriptive measures for the variables (univariate statistics)
indstd
Independent variable standardization vector
depstd
Dependent variable standardization vector
Arguments
file
The name (string) of the .ets file or the full path which the data are to be read from. If it does not contain an absolute path, the file name is relative to the current working directory, 'getwd()'. A .CBK and .ETP file have to be of the same name and in the same directory.
