Description Usage Arguments Details Value Author(s) Examples
This function randomly generates models and determines which paths, when removed, tend to reduce the fit of the model substantially.

restrictions = NULL, cutpoint)
|
data |
The correlation matrix to be fit. |
variable.names |
A list of variables names if they're not specified in the correlation matrix. |
paths |
How many paths should be generated? Can be specified as a single value or as a range. See examples. |
prop.arrows |
What proportion of arrows should be correlational? |
iterations |
Number of random models to be generated. |
restrictions |
A matrix containing restrictions on the DE procedure. See details section. |
cutpoint |
An RMSEA value that differentiates between the modes of the two distributions. |
Fife, Rodgers, and Mendoza (2013) noted that DE
distributions are frequently bimodal and commented that a
possible reason for this is that the poor fitting
distribution has one or more “critical paths” that are
missing. This function first generates iterations
random models, then uses the value for cutpoint
to
identify which paths exist in the right versus left side
of the cutpoint.
returns a matrix the specifies which paths are contained in the "highMode" versus "lowMode" datasets
