GroupSeq: A GUI-based program to compute probabilities regarding group
sequential designs
The package provides a Tcl/Tk-based graphical user interface. It
enables the construction of group sequential designs based on normally
distributed test statistics, and particularly to compute critical
boundaries, power, drift, and confidence intervals for such designs. All
computations are done via the alpha spending approach by Lan-DeMets.
Various alpha spending functions are made available to the user for this
purpose.
