三、在PROC REPORT OUTPUT 中加入computed variable(自定义计算变量) 1DATA natparks;2INFILE'C:\MyRawdata\parks.dat';3INPUT Name $1-21Type $ Region $ Museums Camping; RUN;45*COMPUTENew variables that are numericandcharacter;6PROCREPORT DATA=natparks NOWINDOWS HEADLINE;7COLUMNName Region Museums C...
TABLEpage-dimension, row-dimension, column-dimension; the TABLE statement tells SAS how to organize your table and what numbers to compute. 3. proc sort,其他过程都假设了数据已经进行了排序,所以如果数据还没有排序, 那么在分析之前要用 proc sort 排序。 4.put和file 共用:put是输出报告,output是向数...

The Data step in SAS(R) 6.12 is the recipient of 50+ new functions. These new functions are broken into the following groupings data set functions, external file functions, library and catalog functions, special functions, variable functions, and statistical functions. The objective of this ...
宏用来处理重复工作最好，比如你需要跑10个回归，用proc reg...，这10个回归其他都一样，就是因变量...

A self-service, on-demand compute environment for data analysis and ML models increases productivity and performance while minimizing IT support and cost. In this Q&A, an expert explains why a developer workbench is an ideal environment for developers and modelers. ...
Predictive models use known results to develop (or train) a model that can be used to predict values for different or new data. Modeling provides results in the form of predictions that represent a probability of the target variable (for example, revenue) based on estimated significance from a...
A SAS programmer had many polynomials for which he wanted to compute the real roots. By the Fundamental Theorem of Algebra, every polynomial of degree d has d complex roots. You can find these complex roots by using the POLYROOT function in SAS IML. The programmer only wanted to output Read...
