三道题我的code分别如下 由于我的是sas portable所以我找不到file应该放在哪里 然后就不能用infile= =

Q1:

DATA weight_club;

INFILE 'weight_club.txt' DLM = ',';

INPUT IdNumber Name$ Team$ StartWeight EndWeight;

RUN;   

Q2:

DATA weight_club;

INFILE 'weight_club.txt' DLM = ',';

INPUT IdNumber Name$ Team$ StartWeight EndWeight;

RUN;   

PROC SORT DATA = weight_club;

BY team;

RUN;

PROC BOXPLOT DATA = weight_club;

PLOT StartWeight * team;

Run;

Q3:

DATA weight_club;

INPUT IdNumber Name$ Team$ StartWeight EndWeight;

changeweight = StartWeight - EndWeight;

Proc Univariate data = weight_club;

Var changeweight;

Histogram changeweight;

Title "Histogram of change in weight';

Run;

提前谢谢大家啦！~~~
