I would like to confirm the following issue:
1. How did the IWRES be calculated from the output data? Is the IWRES=(DV-predicted)/weight ?
2. what is detail calculation information of LOESS regression including (1) degree of local polynomials, (2) smoothing parameter, and (3) weight function in the IWRES vs IPRED (or IWRES vs IVAR )?
Thanks in Advance
