Computes the fit (Generalized TEFI) of a hierarchical or correlated bifactor
dimensionality structure (or hierEGA
objects) using Von Neumman's entropy
when the input is a correlation matrix. Lower values suggest better fit of a structure to the data
genTEFI(data, structure = NULL, verbose = TRUE)
Returns a three-column data frame of the Generalized Total Entropy
Fit Index using Von Neumman's entropy (VN.Entropy.Fit
) (first column), as well as
Lower.Order.VN
- TEFI for the first-order factors (second column), and
Higher.Order.VN
, the equivalent for the second-order factors.
Matrix, data frame, or hierEGA
object.
Can be raw data or correlation matrix
For high-order and correlated bifactor structures,
structure
should be a list containing:
lower_order
--- A vector (length = ncol(data)
) representing the first-order structure
(numbers or labels for each item in each first-order factor or community)
higher_order
--- A vector (length = ncol(data)
or number of lower_order
communities)representing
the second-order structure (numbers or labels for each item in each second-order
factor or community)
Boolean (length = 1).
Whether messages and (insignificant) warnings should be output.
Defaults to TRUE
to see all messages and warnings for every
function call.
Set to FALSE
to ignore messages and warnings

# Example using network scores
opt.hier <- hierEGA(
data = optimism, scores = "network",
plot.EGA = FALSE # No plot for CRAN checks
)
# Compute the Generalized Total Entropy Fit Index
