JAB                     Transforms a t-statistic from a glm or lm
                        object into Jeffreys' approximate Bayes factor
JAB_plot                Plots JAB as a function of the p-value
JABp                    Transforms a p-value into Jeffreys' approximate
                        Bayes factor
JABt                    Transforms a t-statistic into Jeffreys'
                        approximate Bayes factor
alphaN                  Set the alpha level based on sample size for
                        coefficients in a regression model
alphaN_plot             Creates a plot of alpha as function of sample
                        size for each of the four prior options
