将t得分添加到sas中的现有数据集

Question

How do I add a new variable with a score in an existing dataset in SAS? 如何在SAS中的现有数据集中添加带有分数的新变量？

proc standard data=orig out=age_t mean=50 std=10; 
var age ;
run;

I want to create a new variable age_t in the original dataset with the t score for every observation 我想在原始数据集中使用每个观察结果的t分数创建一个新变量age_t

Answer 1

Left Join your original table with the Proc Standard output. Left Join原始表和Proc Standard输出。 Full code below: 完整代码如下：

Creating Dummy Data: 创建虚拟数据：

data orig;
input name $ age ;
datalines;
jackieChan 50
Tom 70
Lee 45
Tim .
Sarah 29
Rose 33
;

Saving Standard output to new table "stnd_age": 将标准输出保存到新表“ stnd_age”：

proc standard data=orig out=stnd_age mean=50 std=10; 
var age ;
run;

Left Joining Orig table with stnd_age: 使用stnd_age左加入Orig表：

proc sql;
create table want as 
select orig.* , stnd_age.age as age_t
from orig left join stnd_age on orig.name=stnd_age.name;
quit;

Result: 结果：

name=Sarah age=29 age_t=39.873841923 
name=Tim age=. age_t=. 
name=Tom age=70 age_t=65.189237115 
name=jackieCh age=50 age_t=52.840263851
