Wreck-it Reg

A Stata package to "wreck" any regression with a variable being transformed according to log(+1) or IHS (when there are zeros or negative values in the data) by applying a scaling factor on the transformed variable to achieve an arbitrary coefficient or semi-elasticity estimate.

For a solution to this problem, see the package tregs which performs transformations that result in estimates that do not depend on the measurement units (scaling) of the data. These are the transformations characterized by Thakral and Tô (2024).


The following paper explains the problems that arise with these types of transformations:
