A: Statistical Analysis System(SAS) is a combined set of software products.
A: To run the program successfully, and you have the following essential elements:
For, e.g., In file ‘H:StatHWyourfilename.dat’;
A: The data types in SAS are Character and Numeric.
A: The basic structure of SAS consists of
== DATA step, that recovers and manipulates data.
==PROC step is to interpret the data.
A: SAS informats are of three categories,
A: Some fundamental concept of SAS include,
A: A SAS data set is a file consisting of two parts
A: An Informat is a specification that is to read the raw data, while a Format is a layout specification for how a variable should be displayed.
A: There are five ways to do a “ table lookup” in SAS that includes:
A: The default statistics that PROC MEANS creates are as follows:
A: Basic programming errors appear in SAS are as follows:
A: In SAS, PROC steps process and analyze data as a SAS data set. It controls a library of routine that performs takes on SAS data set option such as sorting, listing, and summarizing.
A: Factor analysis is a common term for a family of a statistical method associated with the reduction of a set of an observable variable in terms of a small number of inactive factors. The main aim of factor analysis is data reduction and summarization.
A: Two steps used to create a permanent SAS data set
A: RUN-Group processing enables to submit a PROC step by using a RUN statement without closing the procedure.
A: The ‘’FLOOR’’ returns the highest integer less than or equal to the argument.
While the ‘CEIL’’ function remits the smallest integer greater than or equal to the argument.
A: %INCLUDE statement reads a whole file into the current SAS program you are running and submits the file to the SAS System right away.
A: The Program Data Vector (PDV) is an analytical area of memory that is created during data processing. It builds a dataset of single observation at a time. An input buffer occurs at the time of compilation that carries a record from an external file.
A: By using Obs=0, you can debug and test your SAS program and the system option to trace the program execution in the log.
A: Proc summary is used to create tables of summary statistics as well as complex summary data sets. The user has great options that can be used to customize the procedure to produce.
A: Delimiter Sensitive Data (DSD) option edits how SAS handles delimiters when we use list input and sets the existing delimiter to a comma. When you identify DSD, SAS treats two successive delimiters in a row as a missing value, it ignores quotation marks as part of your data, and it also ignores delimiters in data values enclosed in quotation marks.
A: To check errors, use the log, and for data validation, we use Proc Means, Proc Freq, or sometimes Proc print to see how the data appears.
A: To include or exclude the particular data set you can use Drop, Keep statement, and data set options.
A: Function expects argument values to be supplied across an observation in a SAS data set while procedure assumes the value of one variable per observation.
A: PROC SQL is a simultaneous process for all the observations. The PROC SQL works as follows:
A: Some of the SAS functions are as follows:
A: The tranwrd function helps to remove or replace all the occurrences of a pattern of characters within a character string.
A: Before SAS 9.1, the data sets could contain around 32,767 variables but, in SAS 9.1, the maximum number of variables in the SAS data set is limited by the resources available on the computer.
A: The Nodup option eliminates the duplicate observations where the values in all the variables are repeated, while the Nodupkey option eliminates duplicate observations where the value of the variable registered in the By statement is repeated.
A: The scrubbing procedures in SAS is to Proc Sort with the Nodupkey option. It helps to eliminate duplicate values.
A: To test the debugging in SAS, you can use the Debug clause after ‘/’ in the data statement.
A: We can generate test data with no input data by using a PUT statement and Data Null.
A: The SUBSTR function is used to abstract substring from a character variable.
A: Stop statement aim the SAS to stop processing the on-going data step at once and continues processing the statement after the end of the existing data step.
A: The features of SAS are as follows:
A: You can use the output statement to save summary statistics in a SAS data set. This information can be used to create customized reports to save historical information about the process.
You can use the options in the OUTPUT statement to
