Informative Simultaneous Confidence Intervals.

informativeSCI

informativeSCI can be used for calculating informative lower simultaneous confidence bounds for a given graphical test procedure and given information weights. Furthermore, it can help to find the right information weights for the bounds.

Installation

You can install the development version of informativeSCI from GitHub with:

install.packages("devtools")
library(devtools)
install_github("LianeKluge/informativeSCI")

Otherwise just use the current version from CRAN.

Usage

The main function of the package is the -function for calculating informative lower simultaneous confidence bounds for a given graphical test procedure and given information weights. The -function can help to find the right information weights for the -algorithm. The - and -functions can help to determine how accurate a (numerical) approximation of the true informative lower SCI-bounds is. For examples, see the Example sections of the documentation pages.
