讲一讲 SAS 9.3

关注inginging~~

想体验下SAS9.3的新画图功能， 可惜一直没有搞到9.3.

9.3的画图功能在ODS上进一步增强。值得学习。
PROC SGPLOT gives PBSPLINE statement which can creates a fitted penalized B-spline curve. Do you know how different it is to the cubic spline curve provided in PROC GPLOT with symbol i =sm**? This question was from variogram plot from spatial analysis where LOESS method is too slow to bear.
Thanks in advance,
