在SAS 中使用函数的一般语法如下。 1 FUNCTIONNAME(argument1, argument2...argumentn)这里的参数可以是常量、变量、表达式或其他函数。 功能类别 根据其用途,SAS 中的功能分为以下几类。 数学 Date and Time 特点 截断 各种各样的 数学函数 这些是用于对变量值应用一些数学计算的函数。
有一点点类似于R语言中的function函数,或者python中的自定义class,为了提高编程效率,macro是不得不学习的内容。 宏和宏变量 SAS宏代码包括两个基本部分:宏命令和宏变量。宏变量通常加一个“&”作为前缀,而宏命令通常加一个“%”作为前缀,两者可以互相独立存在。 局部VS全局 宏变量有局部宏变量和全局宏变量。如果在...
SAS has a wide variety of in built functions which help in analysing and processing the data. These functions are used as part of the DATA statements. They take the data variables as arguments and return the result which is stored into another variable. Depending on the type of function, ...
Ifdayis missing, then it will be imputed to either 30 or 31. if it is feb month then 28 or 29 Imputation flag is added with values as ‘D’ or ‘M’ if any dates is imputed. There are several ways toget the last day of the month,but most easiest way is usingINTNXfunction with...
