用SAS进行数据分析:报表与图形输出过程汇总

如何用SAS进行数据分析:下面我们就对报表与图形输出过程汇总

*Tabulate过程分类汇总;

proc tabulate data=need;
 class brand;
 var ts9 ts10;
 table brand all,(ts9 ts10)*(n sum mean);
 keylabel n=”用户数” sum=”发送总量” mean=”人均发送”;
 label brand=”品牌” all=”总计”  ts9=”9月” ts10=”10月”;
run;

*Means过程输出简单统计量;

proc means data=need n sum mean maxdec=2;
 var ts9 ts10;
 label ts9=”9月” ts10=”10月”;
run;

*Univariate过程输出简单统计量;

proc univariate data=need;
 var ts10;
run;

*Freq过程输出离散变量分布情况;

proc freq data=need;
 tables brand sex;
run;
*Corr过程计算两变量之间的相关关系;
proc corr data=need;
 var ts10 ts9 fee10 fee9;
run;
*Gplot绘制散点图和曲线图;
proc gplot data=need;
 symbol i=none v=* color=blue;
 plot ts10*ts9;
quit;
proc gplot data=need;
 symbol i=join v=* color=blue;
 plot ts10*ts9;
quit;
*绘制直方图;
goptions reset=goptions;
proc gchart data=need;
 vbar sex;
quit;
*绘制三维直方图;
proc gchart data=need;
 vbar3d sex;
quit;
*绘制横向直方图;
proc gchart data=need;
 hbar sex;
quit;
*绘制三维横向直方图;
proc gchart data=need;
 hbar3d sex;
quit;
*绘制饼形图;
proc gchart data=need;
 pie sex/type=percent;
run;
*绘制三维饼形图;
proc gchart data=need;
 pie3d sex/type=percent;
run;
*绘制环形饼形图;
proc gchart data=need;
 donut sex/type=percent;
run;
*绘制三角形面积图;
proc gchart data=need;
 star sex/type=percent;
run;
*绘制三维分类直方图;
proc gchart data=need;
 block sex/group=brand;
quit;
*G3D过程用来绘制三维曲面;
data test;
  do x=-3 to 3 by 0.1;
    do y=-3 to 3 by 0.1;
     z=x**2+y**2;
     output;
 end;
 end;
run;
proc g3d data=test;
 plot x*y=z;
run;
*GCONTOUR过程则是画出曲面的等高线图;
proc gcontour data=test;
 plot x*y=z;
run;
