sgpv

The sgpv package contains functions to calculate the second-generation p-value, its associated delta-gap, and the false discovery risk or false confirmation risk for an alternative or null finding (sgpv = 0 or sgpv = 1) when assumptions are made about the distributions over the null and alternative spaces.

Example

The sgpvalue() function calculates the second-generation p-value and delta-gap (if applicable) for uncertainty intervals with lower bounds est.lo and upper bounds est.hi and an indifference zone (i.e. interval null hypothesis) of (null.lo, null.hi). Note that this example is in terms of odds ratios, and the second-generation p-value should be calculated on the "symmetric" scale, i.e. log odds ratios in this case.

library(sgpv)
lb = log(c(1.05, 1.3, 0.97))
ub = log(c(1.8, 1.8, 1.02))
sgpvalue(est.lo = lb, est.hi = ub, null.lo = log(1/1.1), null.hi = log(1.1))
