Can be "default", "makowski2019" or a custom set of rules().

...

Not directly used.

Rules

  • Default (i.e., equivalent to p-values)

    • pd <= 0.975 - not significant

    • pd > 0.975 - significant

  • Makowski et al. (2019) ("makowski2019")

    • pd <= 0.95 - uncertain

    • pd > 0.95 - possibly existing

    • pd > 0.97 - likely existing

    • pd > 0.99 - probably existing

    • pd > 0.999 - certainly existing
