Bayes Factor for Paired or One-Sample t-Tests


Sample Size

t-value

Scale r on effect size



Summary: This calculator computes Bayes factor for paired or one-sample t-test designs.

Priors: Outputs are provided for three priors:
i. Jeffrey-Zellner-Siow Prior (JZS, Cauchy distribution on effect size)
ii. Unit-Information or Scaled-Information Prior(Normal prior on effect size)
iii. Unit-Information Prior with known variance (prior that underlies BIC)
