Details

The DESCRIPTION file: tools:::Rd_package_DESCRIPTION("tailTransform") tools:::Rd_package_indices("tailTransform") The package contains five items: (i) a function ttrans() that symmetrically shortens the tails of pair differences for graphical display, (ii) three plotting functions, boxplotTT(), boxplotTTlist() and boxplotBlockDesign(), that aid 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:10.1080/00031305.2022.2063944>
