Converts numeric Bayes factors into categorical evidence levels following conventional thresholds (Jeffreys, 1961; Lee & Wagenmakers, 2013).

Usage

classify_bf_evidence(bf)

Arguments

bf: Numeric vector of Bayes factors (BF10)

An ordered factor with levels:

strong_null: BF < 0.1 - Strong evidence for null hypothesis
moderate_null: BF 0.1-0.33 - Moderate evidence for null
inconclusive: BF 0.33-3 - Evidence is inconclusive
moderate_alt: BF 3-10 - Moderate evidence for alternative
strong_alt: BF > 10 - Strong evidence for alternative

Examples

classify_bf_evidence(c(0.05, 0.2, 1, 5, 20))
#> [1] strong_null   moderate_null inconclusive  moderate_alt  strong_alt   
#> 5 Levels: strong_null < moderate_null < inconclusive < ... < strong_alt
