# A simple general formula for tail probabilities for frequentist and Bayesian inference

@article{Fraser1999ASG, title={A simple general formula for tail probabilities for frequentist and Bayesian inference}, author={D. A. S. Fraser and Nancy Reid and J. Wu}, journal={Biometrika}, year={1999}, volume={86}, pages={249-264} }

SUMMARY We describe a simple general formula for approximating the p-value for testing a scalar parameter in the presence of nuisance parameters. The formula covers both frequentist and Bayesian contexts and does not require explicit nuisance parameterisation. Implementation is discussed in terms of computer algebra packages. Examples are given and the relationship to Barndorff-Nielsen's approximation is discussed.
