Examples

grm_dt <- genData(eta = genTheta(nsample = 500, nfac = 1),
                 ipar = genIRTpar(nitem = 10, ncat = 3, nfac = 1))

fit <- runGRM(dat = grm_dt,
            lav.syntax = genLavSyn(dat = grm_dt, nfac = 1),
            estimator = "WL")
FSplot(fit, type = "histogram", hist_bins = 20, base_size = 16)
