第一次发帖 求大米呀 ..
考试时界面不卡 输入也没有延迟 运行也很快
就是 control+v control+c 复制的粘贴的时候有点慢. ----
提前半小时check-in check-in 完后也没有等到开始考试的时间 就可以开始考试了
第一次考 还是有点慌 第一题出来的时候还以为sample question. Waral dи,
然后看到右上角的倒计时 才意识过来这已经是考试题目了. 1point3acres
备考时间一个月 期间断断续续看了一下 本身在学sas软件 所以有一点基础知识
做了以便120 50 做了四遍70 (超重要)然后四五遍机经每日一遍 968 out of 1000. Χ
考试用的 sas studio
lab 题目 和机经不太一样 但是在前辈的机经中都出现过
印象深刻的题目. 1point3acres
proc import 中如果没有replace option 但是output已经存在 应该怎么办
A Sas will name it output2;. Χ
B sas will overwrite the dataset
C sas will not replace the dataset but write a note in the log
D sas will prompt user to rename the new data set.-baidu 1point3acres
还是import
如果import的 data set有1-10 observations have 10 characters long;-baidu 1point3acres
and the remaining observations have 30 character long; -baidu 1point3acres
and some observations have different attributes;
A format
B GUESSINGROWS
C lable
D length. ----
就这两个新题. 1point 3acres
lab1 把full_name 分成last_name first_name (Smith, John)
1.哪个last_name出现最多次
2.出现了多少次
3.first_name=‘XU XIN’ 的出现了几次;. 1point 3acres
lab2 three data set june august july
1 stepC in june 3rd
2 min stepB in August 20
3 step A in june 15
lab3 给你一个input15, 查看enconding 和label
直接proc content data=.--
lab4 age <=39 young
40<age<=65 mid
age> 65 notasyoung. 1point 3acres
1 observations of young data set
2 #34 in mid;
3 忘了
lab5 给你一个input 然后用proc transpose 转成题目中给的表的样式(题目会告诉你转置后的rows=52)
*****所以一定要记清楚ID 是变成标题名字的 by 是不变的 var 是要转置的
1 the number of variable
2 #1595 observation
lab6 merge two data set and output 3 data set
a b 都包含的变量 then 输出
只在a then 输出
只在b then 输出
lab7 error 先复制code然后新建program
很简单 drop=age; 改成 drop age;. Waral dи,
然后data set younger 改成young
proc freq var 改成table;
选择题
大部分都是70题变形
