Broken-stick method for detection of significant factors
Description
This function provides a simple way to determine the number of significant
factors in a factor analysis. This is done by comparing the eigenvalues of
each factor with those expected from a broken-stick distribution.
Usage
brStick(eigs)
Arguments
eigs
numeric. Vector of eigenvalues
Value
Returns the number of significant factors.
References

a comparison of heuristical and statistical approaches." Ecology 74.8 (1993):
2204-2214.
Examples
mod1 <- enfa(x = climdat.hist, s.dat = ABPR, field = "CODE")
brStick(s.factor(mod1))
