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.
You can install the development version from GitHub by running
install.packages("devtools")
library(devtools)
install_github("LianeKluge/informativeSCI")Otherwise just use the current version from CRAN.
The main function of the package is the
informSCI-function for calculating informative lower
simultaneous confidence bounds for a given graphical test procedure and
given information weights. The explore_q-function can help
to find the right information weights for the
informSCI-algorithm. The inExactSCI- and
notInExactSCI-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.
