如何防止中点延长 [英] how to prevent midpoints from extending

问题描述

我有以下代码

proc univariate data=work.dataset noprint;
    histogram value / barwidth=.05 midpoints=(-2.45 to 2.45 by .05) outhist=data_bin nochart;

运行；我在日志中收到此警告消息警告:MIDPOINTS= 列表已扩展以容纳数据.

run; I get this warning message in the log WARNING: The MIDPOINTS= list was extended to accommodate the data.

我基本上想防止中点延伸我希望它们从 -2.5 开始到 2.5 结束.

I basically want to prevent the midpoints from extending I want them to start from -2.5 and end at 2.5.

已解决

只需要在 proc 步骤之前对数据进行 bin 处理

Just need to bin the data before the proc step

推荐答案

SOLVED

基本上在数据创建点，我将变量 value 的值限制在 -2.5 到 2.5 的范围内.

Basically at data creation point I cap the values of variable value in between the range of -2.5 and 2.5.

代码还是一样，只是在data里加了一个if语句来剔除-2.5到2.5的数据

The code still remains the same just added a if statement in data to cull the data from -2.5 to 2.5
