Need to compare Bayes BF10 as calculated by JASP with equations give in

Wagenmakers, E.-J. (2007). A practical solution to the pervasive problems ofp values. [journal article]. Psychonomic Bulletin & Review, 14(5), 779-804. https://doi.org/10.3758/BF03194105

JASP gives same classic ANOVA as SPSS

see attached spread sheets for JASP results for Both NOVAS and calculations of BF10

deltaBIC from equations based on F should equal 2 ln(BF10) from Bayes ANOVA

Cases Sum of Squares df Mean Square F p η² SSerr/(SSerr+effect) dfError/(dfError+Feffect*dfEffect) Nln(SSratio) dfEffect*ln(N) deltaBIC BF10
