Inspect statistical diagnostics — diagnostics

Return diagnostic checks, observed values, thresholds, and interpretations retained by a gtstats result.

Usage

diagnostics_stats(
  x,
  format = c("table", "tibble"),
  title = "Diagnostics",
  subtitle = NULL,
  view = c("readable", "audit")
)

Arguments

x: A gtstats result.
format: Output format: "table" (default) or "tibble".
title, subtitle: Optional table heading used for format = "table".
view: Either "readable" (the default, plain-language headings) or "audit" (raw diagnostic codes retained by the analysis object).

Value

A tibble or gt_tbl.

Examples

result <- compare_groups(mtcars, variable = vs, group = am)
diagnostics_stats(result)

vs
Comparison design
independent
Independent observations
Defined by the study design
Independent comparison; confirm independence from the study design.
vs
Variance assumption
not applicable
var_equal = FALSE
Applies only to independent parametric continuous comparisons
`var_equal` does not alter paired, categorical, ordinal, or rank-based routes.
vs
Automatic test selection
Chi-square test
5.69
No expected count below 1 and no more than 20% below 5
Independent categorical outcome; expected cell count guidance was met (no expected count below 1 and no more than 20% below 5); selected Pearson chi-square test.
vs
Expected cell counts
guidance met
5.69
No expected count below 1 and no more than 20% below 5
Fisher's exact test is selected automatically when expected-count guidance is not met.
