Test-of-fit summary as a table

Returns the model, estimation method, trait chi-square, calibration and person fit-residual moments, fit-location correlations, the approximate asymptotic chi-square flag count, and disordered-threshold count as a two-column table. MFRM and EFRM summaries label their fitted item-by-facet or item-by-frame columns as response cells. A wholly unavailable probability family is labelled as unavailable; a partial family reports the tested and unavailable counts.

Usage

fit_summary_table(fit)

Arguments

fit

A fitted object from rasch, or a paired-comparison fit from btl (which reports its own headline set: convergence, pairwise chi-square, object separation, thresholds structure, and dependence effects when estimated).

Value

A data frame with columns statistic and value.

Examples

set.seed(1)
d <- seq(-2, 2, length.out = 6)
X <- matrix(rbinom(300 * 6, 1, plogis(outer(rnorm(300), d, "-"))), 300, 6)
colnames(X) <- paste0("I", 1:6)
fit_summary_table(rasch(X))
