Uniformly most powerful log odds ratio of a one-sided conditional test

Description

Solves the conditional KL divergence of the alternative at logOdds from logOddsNull equal to log(1 / alpha), searching up to searchBound from logOddsNull in the direction of alternative.

Usage

solveUmpLogOdds(
  na,
  nb,
  totalSuccesses,
  alpha,
  alternative = c("greater", "less"),
  logOddsNull = 0,
  searchBound = 100
)

Arguments

na	number of observations in group A per data block, one value or one per block.
nb	number of observations in group B per data block, one value or one per block.
totalSuccesses	nonnegative integer, the total successes ya + yb in the table, at most na + nb.
alpha	numeric in (0, 1) that specifies the tolerable type I error and the null rejection rule e >= 1/alpha.
alternative	"greater" or "less", the side searched.
logOddsNull	numeric, the null log odds ratio.
searchBound	numeric > 0, the width of the search interval.

Value

A numeric, or NULL with a warning when the target is not reached on the search interval.
