View source: R/bisec.R

Description

Running bisection algorithm to search for a2, the minimizer of (log((a2)^dea1*(1-a2)^dea2-delta))^2

Usage

1
bisec(delta, dea1, dea2, upbd, lowbd)

Arguments

delta

Test statistic in Han et al. (2012), delta = (ttot1/(ttot1+ttot2))^dea1*(ttot2/(ttot1+ttot2))^dea2;

dea1

first parameter in Beta distribution (number of events from the first arm)

dea2

second parameter in Beta distribution (number of events from the second arm)

upbd

upper bound of a2

lowbd

lower bound of a2

Value

a2

Examples

1
bisec(-74.4824, 33, 98, 1, 0.252)
