mult
(Package: MChtest) :
Calculation to Convert Stored cb values to K values.
Calculates frac{(p^r)* ( (1-p)^(n-r) )}{ β(r,n-r)}. This calculation is used to convert stored cb values to K values in MCdesign objects. For internal use only.

The package performs Monte Carlo hypothesis tests. It allows a couple of different sequential stopping boundaries (a truncated sequential probability ratio test boundary and a boundary proposed by Besag and Clifford, 1991). Gives valid p-values and confidence intervals on p-values.

rrisk
(Package: MChtest) :
Calculate resampling risk and expected resampling size
Calculates for a particular stopping boundary the resampling risk of making the wrong accept/reject decision. Can be calculated for different distributions of the p-value. If type="p" then assume point mass at pparms. If type="b" then assume a beta distribution with two shape parameters given by pparms.
