wcs_power_best_binomial {ssutil} | R Documentation |
Worst‐Case Scenario Power for the Best Binomial Group
Description
Searches for the probability in the best‐performing group that yields the lowest statistical power, given an indifference zone specification, a number of groups, and a number of subjects per group.
Usage
wcs_power_best_binomial(dif, ngroups, npergroup)
Arguments
dif |
Numeric. Indifference zone specification (difference threshold). |
ngroups |
Integer. Number of groups to compare. |
npergroup |
Integer. Number of subjects per group. |
Details
Defines an internal function fx
that wraps power_best_binomial
with the supplied parameters, then uses optimize
over the interval [0,1]
to find the probability p1
that minimizes the resulting power.
Value
A named list with components:
- p1
Numeric. Probability in the best group that yields the minimum power.
- minimum_power
Numeric. The minimum power achieved at
p1
.
