Dataframe |
useDeviations |
Whether to code the mode using deviation thresholds (default = TRUE) |
printFit |
Whether to print information about the fit achieved (default = FALSE) |
use |
parameter (default = "any") |
tryHard |
'no' uses normal mxRun (default), "yes" uses mxTryHard, and others used named versions: "mxTryHardOrdinal", "mxTryHardWideSearch" |
