News

Changes in version 0.7

added a progress argument to gCD(), LD(), and GOF() to print the progress of the iterations

Changes in version 0.5

several orgainizational overahauls
split LD() into LD() and GOF() for better clarity
avoid masking lavaan::sem with sem::sem

Changes in version 0.4

better use of the parallel package for faster computing in most functions (most notably in the forward.search implementation)
numerical tests added for better package stability
more flexible passing of lavaan-type models and other functions used within the package
