Computes MGCFA model for a given pair of groups

Usage

pairwiseFit(
  model,
  data,
  group = "cntry",
  constraints = c(""),
  pairs.of.groups = NULL,
  message = "Fitting pairwise lavaan models",
  shiny = FALSE,
  signed = F,
  quiet = F,
  ...
)

Arguments

model: Model in lavaan syntax
data: Data object
group: Character. Group variable name.
constraints: Can be "", "loadings", or c("loadings", "intercepts").
pairs.of.groups: Full list of pairs of groups, used in shiny only.
message: Notification in shiny.
shiny: If it is executed in shiny environment.
signed: Only for DMACS, if the signed version should be used. See Nye et al 2019
...: Arguments passed to cfa function.

Value

The function returns matrix of fit indices for multiple group CFA models fitted to each possible pair of groups.

Details

Mostly for internal use within incrementalFit

Examples

if (FALSE) { # \dontrun{ 
 pairwiseFit(model = "F =~ impfree + iphlppl + ipsuces + ipstrgv", 
             data = ess6, 
             group = "cntry", 
             constraints = "loadings")
} # }
