实际上,您可以在PROC POWER中直接通过说power=0.8 to 0.95 by 0.01来完成此操作。 PROC POWER不会以本机方式输出数据集,但您可以输出驱动输出的底层表。如果你转动ods trace on,你可以看到表的名字叫做output。我们可以选择它并将其作为名为power的表输出: proc power; twosamplefreq test=pchi groupproportions =...
设定α=0.05,1-β=0.8。则SAS程序为:proc power; /*调用proc power命令*/twosamplefreq /*指定估计的类型是两组率比较*/groupproportions=(0.83 0.71) /*指定两组的有效率*/power=0.8 /*指定把握度为0.8*/ntotal=.; /*表明要对样本含量进行估计*/run;最终计算所得样本量为384例。

Hello, I would like to get a range of both the power and totlaN output from proc power while using the current ntotal = 3514. For example, I would like this output table: N power 100 .10 200 .20 300 .30 proc power; twosamplefreq test=pchi sides = 2 alpha = 0.05 groupproporti...
SAS里面的基本回归分析:PROC REG 类似于R中的lm(),这个实在是没什么好说的了,最基本的最小二乘法。 DATA hits; INFILE 'c:\MyRawData\Baseball.dat'; INPUT Height Distance @@; RUN; * Perform regression analysis; PROC REG DATA = hits;
调用方式为:LIBNAME WWW 'C:\HULP';PROC 过程名 DATA=WWW.ABC;再写其他SAS语句。④特殊的数据集名 DATA _NULL_; 和 DATA _LAST_;前一个语句表明只想用PUT语句来输出一些结果, 但不想创建SAS数据集,可减少使用计算机的资源; 后一个语句表明SAS系统使用一个称为_LAST_的特殊自动变量来保留在一个SAS程序里...
