1:where and if the most essential differences, as well as some small differences1.1:the WHERE statement examines what was in the input page buffer and selects observations before they was loaded in the P Rogram data vector, which results in a savings in CPU operations (where to filter from buffer and then read into PDV)The subsetting IF statement loads all observations sequentially to the program data vector. If The statement finds a match and the statement are true, then the data is processed a

SAS hard Drive, is a serial connection to the next generation of SCSI technology, the use of serial technology to achieve higher transmission speed, and by shortening the connection line to improve the internal space. SAS is a parallel SCSI interface that develops a new interface. Improves storage system performance, availability, and scalability, and provides compatibility with SATA hard drives. Character

Recently, the SAS code of the old system in the calculation process, there are less data, I passed a few times to check the code, or did not find the problem. Finally, with the help of a senior colleague, I found the cause of the problem, but in retrospect I still feel that I am not careful enough and how to debug the SAS code is not proficient, description as follows: The code is mainly the following code

In general, we will use Excel to statistical test results, in addition to Excel, there are SAS and other software, but also can be statistical test results, I am also a beginner of SAS, now I would like to introduce you to the simple use of SAS, with my constant learning statistics knowledge, 　　 I would also like to delve into the features of these statistics sof
