The HPSPLIT Procedure

Interval Input Binning Details

PROC HPSPLIT places interval input variables into bins. You can specify the number of bins by using the INTERVALBINS= option in the PROC HPSPLIT statement. Each bin except the last spans the range

\begin{equation*}  \left[ \frac{v_{\mi{max}} - v_{\mi{vmin}}}{\mi{intervalbins}}\mi{bin} + v_{\mi{min}}, \frac{v_{\mi{max}} - v_{\mi{min}}}{\mi{intervalbins}}\left(\mi{bin}+1 \right) + v_{\mi{min}} \right) \end{equation*}

where $v_{\mi{max}}$ and $v_{\mi{min}}$ are the maximum and minimum value of the respective variable and bin is the bin, which is an integer in the range

\begin{equation*}  \left[0, \mi{intervalbins} \right) \end{equation*}

For the largest bin, the end of the bin range is inclusive.
