Analyst Application Overview
Overview
The Analyst Application is a point-and-click interface that provides easy access to basic statistical analyses. The application is intended for students and novice SAS users as well as for researchers and analysts who are already familiar with the SAS System and would like to use a graphical user interface.
The application provides a wide range of statistical and graphical tasks. You can compute descriptive statistics, perform simple hypothesis tests, and fit models with analysis of variance and regression. Other tasks include repeated measurements, mixed models, survival analysis, and multivariate analysis. The application also provides some tasks not covered by SAS procedures, such as sample size and power computations. In addition, you can produce several types of graphs, including histograms, box-and-whisker plots, probability plots, scatter plots, contour plots, and surface plots.
You can analyze data from a variety of sources with the Analyst Application. You can import Excel, Lotus, and dBase files, input existing SAS data sets, or enter the data values yourself. The data are displayed in a Data Table in which columns correspond to variables and rows correspond to observations or cases. You can edit individual elements in the data table, create new variables, create subsets and random samples of the data, and transpose the data.
You can access the tasks from pull-down menus, a customizable toolbar, or an index of commonly used terms. The tasks are not simply interfaces to existing SAS procedures; they are a combination of procedure invocations and DATA steps required to perform a complete analysis. While you need not be aware of the underlying SAS code, you can view and save it if you are interested in using it in your own programs. The analysis results, HTML output, plots, output data sets, and SAS code are presented in separate windows, and all of this output is managed in a Project Tree in conjunction with the Data Table. You can save both text and graphical results as entries in a SAS catalog, as well as save text results in a separate file or print them directly from Analyst.
