Default guidance settings for nomologR

The numerical values returned by this function are teaching/reference points, not universal pass/fail criteria. They are intended to trigger inspection and explanation in downstream nomologR functions.

Usage

nomo_defaults(profile = "teaching")

Arguments

profile

Guidance profile. Only "teaching" is implemented during the initial development series.

Value

A named list of guidance settings.

Details

Each value is a commonly taught reference point from the literature cited in the corresponding analysis function (for example, nomo_efa(), nomo_cfa(), nomo_reliability(), and nomo_validity()). Changing a reference changes which evidence is flagged for review; it never deletes items, respecifies models, or declares validity.

Examples

guidance <- nomo_defaults()
guidance$efa_loading_reference
#> [1] 0.4
guidance$fit_reference
#> $cfi
#> [1] 0.95
#> 
#> $tli
#> [1] 0.95
#> 
#> $rmsea
#> [1] 0.06
#> 
#> $srmr
#> [1] 0.08

# A deliberately stricter loading reference flags more items for review.
