Plot observed CFA fit indices against the simulated null distribution

Faceted histograms of the simulated CFI, RMSEA, and SRMR distributions (one panel per index), with the observed value overlaid as a vertical line. The line is coloured red when the observed value falls outside the chosen percentile of the simulation in the unfavourable direction (CFI from below; RMSEA / SRMR from above), and grey otherwise.

Usage

RMdimCFAPlot(cutoff_res, percentile = NULL)

Arguments

cutoff_res

The list returned by RMdimCFACutoff with output = "list", or the kable returned with output = "kable" (the underlying list is read from attr(., "result")).

percentile

Numeric in (50, 100) or NULL. When supplied, the cutoff and the flagged status are recomputed at this percentile from the simulated distribution stored in cutoff_res (no re-simulation needed). When NULL (default), the percentile that was used by the original RMdimCFACutoff() call is reused.

Value

A ggplot object.

  RMdimCFAPlot(res, percentile = 95) # override (no re-simulation needed)
