Interpret Bayes Factor (BF)
interpret_bf(
bf,
rules = "jeffreys1961",
log = FALSE,
include_value = FALSE,
protect_ratio = TRUE,
exact = TRUE
)
bf |
Value or vector of Bayes factor (BF) values. |
rules |
Can be |
log |
Is the |
include_value |
Include the value in the output. |
protect_ratio |
Should values smaller than 1 be represented as ratios? |
exact |
Should very large or very small values be reported with a scientific format (e.g., 4.24e5), or as truncated values (as "> 1000" and "< 1/1000"). |
Argument names can be partially matched.
Rules apply to BF as ratios, so BF of 10 is as extreme as a BF of 0.1 (1/10).
Jeffreys (1961) ("jeffreys1961"
; default)
BF = 1 - No evidence
1 < BF <= 3 - Anecdotal
3 < BF <= 10 - Moderate
10 < BF <= 30 - Strong
30 < BF <= 100 - Very strong
BF > 100 - Extreme.
Raftery (1995) ("raftery1995"
)
BF = 1 - No evidence
1 < BF <= 3 - Weak
3 < BF <= 20 - Positive
20 < BF <= 150 - Strong
BF > 150 - Very strong
