Details

The DESCRIPTION file: tools:::Rd_package_DESCRIPTION("tailTransform") tools:::Rd_package_indices("tailTransform") The package contains three items: (i) a function ttrans() that symmetrically shortens the tails of pair differences for graphical display, (ii) a function boxplotTT() that aids in interpreting and displaying the transformed data, and (iii) an observational study aHDL with three control groups and an unaffected outcome that are intended to reveal unmeasured confounding if it is present.<doi:10.1111/biom.13558>
