A finite set of formatted values cannot be produced from the format. Use the Weekday function on the date to create a new variable and do the analysis on that. And a custom format to map the number back to days of the week. 2 Likes Reply Quentin Super User Re: PROC FR...
returns a SAS date value from the year and quarter Mathematical Functions AIRY(x) returns the value of the AIRY function DAIRY(x) returns the derivative of the AIRY function DIGAMMA(argument) returns the value of the DIGAMMA function ERF(argument) returns the value of the (normal) error funct...
the step will not compile because of the character argument in the mdy function. 答案:A 本题知识点:数据类型的自动转换 在 SAS 中,日期时间是以 1960 年 1 月 1 日 0 时 0 分 0 秒作为起点的。因此,mdy(1,1,1960)=0。 若把日期时间表示为常数时,要使用相应的格式,带单或双引号,在后面紧跟...
