sas sum(of array name * )

SUM is one of the most frequently used SAS ® functions for aggregating numeric variables. Although summarizing data using the SUM function is a simple 

Have you ever noticed your data step repeats the same code over and over? And then thought … there must be a better way. Sure you could use a macro

INTRODUCTION. Most of the row-wise functionality required for data collection reporting and analysis is handled very efficiently by the.

ABSTRACT. Though SAS® DATA Step Arrays have been around for a long time they are one of the more elusive constructs in the SAS System.

ABSTRACT. Do you tend to copy DATA step code over and over and just change the variable? Do you want to learn how to take.

ABSTRACT. Do you need to. • perform repetitive calculations on a group of variables. • create many variables with the same attributes.

Have you ever noticed your data step repeats the same code over and over? And then thought … there must be a better way. Sure you could use a macro

A FUNCTION returns a value from a computation or system manipulation that requires zero or more arguments. And like most programming languages

Many programmers often find the thought of using arrays in their programs to be a daunting task and as a result they often shy away from arrays in their 

To do that you pass the name of the array using the [*] syntax to the SUM function by using the OF operator sum_net_inc=sum(of net_inc[*]); You can use the OF operator with functions such as MEAN MIN and MAX or any other functions that operate on a list of variables mean_net_inc=mean(of net_inc[*]); /* Arithmetic mean (average) */

SAS ARRAY is a set of variables of the same type called “elements” of the arry that you want to perform the same operation on An array name is assigned to the set of variables Then the array name is reference in other DATA step programming to do an operation on the entire set of variables in the array

SAS ARRAY is a set of variables of the same type called the “elements” of the array that you want to perform the same operation on An array name is assigned to the set of variables and then the array name is referenced in later DATA step programming usually a DO loop to do an operation on the entire set of variables in the array

Non-temporary data step arrays demonstrate the real flexibility and versatility of SAS arrays These types of arrays can refer to a series of variables already present in the program data vector ( PDV ) or even create variables while permitting those variables to be referenced via array structures

name of the array elements or other variables in the SAS dataset from which the array elements are taken Although we can use a function name as an array name this is not recommended It can give unpredictable results because SAS will not recognize the function name anymore rather deem it an array name

SAS array is a collection of SAS variables that can be referenced in the Data Step under a common single name The general syntax for defining an array is as follows: ARRAY array-name{dimension} $ length elements (initial values); ARRAY – is the Identifying Keyword for the statement Array-name – is the name we create for the array
