Identifying monotonic and non-monotonic relationships


  • Yitzhaki, Shlomo
  • Schechtman, Edna


We suggest graphical tools that indicate whether the relationship between variables in regression is monotonic. If not, the tools identify sections with different signs and inform on possibilities and types of monotonic transformations that can change the sign of the coefficient.
