3.2单变量分析 proc univariate

语句：

proc univariate data=data-set-name  mu0=... loccount;

var var1;

run;

输出结果：

1.moments

N, mean,std deviation,skewness, uncorrected SS,sum weights,sum observaions,varince,kurtosis,corrected SS,coeff variation,std error mean 

2.basic statistical measures

location:mean,median,mode

variability:range ,variance, std variation, interquartile range

3.tests for location:mu0=...

对均值为...的假设检验结果 

4.location counts

loccount指打印输出大于、不等于、小于被检验均值的所有值

5.extreme observations

默认输出5个极端观测值，可用NEXTROBS更改默认

 

 附 ：也可对一个以上变量进行单变量分析

代码如下：

proc univariate data=data-set-name mu0= num1  num2 ;

var x y;

run;

即可对变量X Y进行单变量分析，并检验均值分别为num1和num2的情况
