pauc: Power-adjustment based on non-parametric estimation of the ROC curve

Description

It is common to use Monte Carlo experiments to evaluate the performance of hypothesis tests and compare the empirical power among competing tests. High power is desirable but difficulty arises when the actual sizes of competing tests are not comparable. A possible way of tackling this issue is to adjust the empirical power according to the actual size. This function implements the "method 2: non-parametric estimation of the ROC curve" in Lloyd (2005). For more details, please refer to the paper.

Usage

pauc(stat_h0, stat_ha, target_range_lower, target_range_upper)

Arguments

stat_h0

simulated test statistics under the null hypothesis.

stat_ha

simulated test statistics under the alternative hypothesis.

target_range_lower

the lower end of the size range.

target_range_upper

the upper end of the size range.

Value

the adjusted power.
