Help Pages

.onAttach	Package Attach Hook Function
add.param	Adds a parameter to the given search table. Checks whether parameter is involved in any (in)equality constraints in a fitted lavaan model
antcolony.lavaan	A function to implement the ant colony optimization algorithm for short form specification searches with the package lavaan.
antcolony.mplus	A function to implement the ant colony optimization algorithm for short form specification searches, either using MPlus directly via 'system' calls or using Mplus indirectly with the package MplusAutomation.
exampleAntModel	Model syntax for the example in the 'antcolony.lavaan' function.
plot	Plot Functions for ShortForm Objects
plot.antcolony	Plot Functions for ShortForm Objects
plot.simulatedAnnealing	Plot Functions for ShortForm Objects
plot.tabu	Plot Functions for ShortForm Objects
refit.model	Given a fitted lavaan model and a search table, refits the model using the search table as specifying what changes should be done (parmeters fixed/freed).
search.prep	Given a fitted lavaan model (e.g., CFA), prepares a table that contains parameters that can be fixed/freed as part of a model specification search.
shortExampleAntModel	Model syntax for the short example in the 'antcolony.lavaan' function.
ShortForm	'ShortForm' package
ShortFormStartup	Create Package Startup Message
simulatedAnnealing	An adaptation of the simulated annealing algorithm for psychometric models.
simulated_test_data	A simulated data set based on a standardized test.
tabu.sem	Given a fitted lavaan model, a search table, and an objective criterion, performs a Tabu model specification search. Currently only supports neighbors that are 1 move away from the current model.
tabuShortForm	Short Form Tabu Search
