如何糾正我正在觀察的錯誤消息？

Question

運行宏％better_means後，我收到一條錯誤消息，但我不確定我必須更改哪些選項才能正確計算彙總統計信息。

      QMETHOD=P2. 
    NOTE: The affected statistics will be missing from the corresponding classification levels.

這是由事實位數（和百分位數）計算，需要大量的存儲與計算它們的（基本上，排隊的一切行動，然後找到5％大關等）的默認方法運行。如果造成你有很多數據，或者你有很多變量或類變量，你可能會遇到這個問題。考慮將你的運行分成多個步驟（也許在一個proc方法中做一些類變量，另一個在另一箇中），或增加SAS可用的內存量。
