RAND, a new SAS function, is an easy-to-use general random number generator, and basically gives "standard distribution." Therefore, to obtain a random number for "non-standard distribution," some additional math work is needed to transform data from "standard" to "non-standard." This paper...
A DATA step is used to split DE VELOP into TRAIN and VALIDATE. The variable U is created using the RANUNI function, which generates pseudo-random numbers from a uniform distribution on the interval (0,1). The RANUNI function argument is an initialization seed. Using a particular number, grea...
PROBIT(p):计算标准正态分布的p分位数。 TINV(p,df>,nc<):计算自由度为df的t分布的p分位数。可选参数nc为非中心参数。 ⒐随机数函数(Random Number Functions) SAS提供了常见分布的伪随机数生成函数。 NORMAL(seed):产生服从正态分布的随机数。seed为0,或5位、6位、7位的奇数。©...

比如插值,插进来变量“形参”(其实混合宏声明的地方的参数就像js中函数function右边小括号里的形参一样, 而调用时传的参数就好像函数调用的时候的实参一样。),直接就给转换成“实参”了 其次,声明混合宏的参数(形参)处,变量等于true不是用双等号(==),而是用冒号(:), 做了一个实验是,这里还可以不写:true;的...
