alpha 
A priori alpha level 
usedFit 
Vector of names of fit indices that researchers wish to get cutoffs from. The default is to get cutoffs of all fit indices. 
onetailed 
If 
nVal 
The sample size value that researchers wish to find the fit indices cutoffs from. 
pmMCARval 
The percent missing completely at random value that researchers wish to find the fit indices cutoffs from. 
pmMARval 
The percent missing at random value that researchers wish to find the fit indices cutoffs from. 
df 
The degree of freedom used in spline method in predicting the fit indices by the predictors. If 
One or twotailed cutoffs of several fit indices with a priori alpha level. The cutoff is based on the fit indices from Model 1 subtracted by the fit indices from Model 2.
