82 observations having zero frequencies or weights were excluded since they do not contribute to the analysis.这是什么问题啊?我已经把变量里面包含零值的记录作了修改,改为很小的数值,0.00001,怎么还会提示有这么多零值?
A more detailed sample should illustrate this problem better. It is not clear what you desire to do for those zeros. Whatever, a new verison of SAS allows you to use zeros options on dealing with zero frequency or weights.
I misunderstood your problem somehow.
In fact zeros option is only working on proc FREQ.
For either proc REG or GLM will exclude those observations with weight as 0 from the analysis.
When you assign a low value of weight to a record, that will contribute very less to the (weigthed) residual sum of squares, and that is also how weight works.
