This option tells SAS what on what line you want it to start reading your raw data file. If the first record(s) contains header information such as variable names, then set firstobs=n where n is the record number where the data actually begin. For example, if you are reading a comma ...
When a procedure uses anAnnotate data set, it reads and interprets the observations one at a time, starting with the first observation and proceeding to the last. The order of the observations in the data set determines the order in which the graphics elements are generated. If the coordinate...

if first.region then do; temp = salary; output; end; if last.region then do; range = salary - temp; output; end; run; What is the number of observation(s) written to the output data set for each region? A. 0 B. 1 C. 2 D. 4 12. The following SAS program is submitted: dat...
For example, if you are reading a comma separated file or a tab separated file that has the variable names on the first line, then use firstobs=2 to tell SAS to begin reading at the second line (so it will ignore the first line with the names of the variables).MISSOV 43、ER This ...

and citizen data scientists. SAS Visual Analytics for SAS Viya first introduces the basics needed to prepare and explore your data, make discoveries, and create a report in SAS Visual Analytics. Then, the second section describes more advanced topics, such as using automated explanation and creatin...
If the value with the hyphen is the first input value for the column,the result is amissing value. If not the first, SAS can pick up leftover data in the buffer from a previous value. 解决方法: A workaround is tocompress out the hyphens and colonsas shown in this example. ...
1:基于前面的描述增加 SAS creates the FIRST.variable and LAST.variable for each variable listed in the BY statement 2:清空变量的方式有不同,The values of the variables in the program data vector are set to missing each time SAS starts to read a new data set and when the BY group changes...
Each set of two variables represents the responses in the first and second periods of the AB/BA crossover design. For example, if you use the CROSSOVER= option and specify VAR x1 x2 x3 x4, then you will get two analyses. One analysis will have x1 as the period 1 response and x2 ...
