The resulting dataset will have one row for each variable identified in the VAR statement. Other options available in the PROC TRANSPOSE statement that can be found in the SAS Help ARRAY - is a SAS keyword that specifies that an array is being defined Arrayname - a valid SAS name that is not a variable name in the data set {n} - the index used to give the number of elements in the array ( A numeric constant/Numeric SAS expression /(*) [$] - used to specify if the elements in the array are Long verses Wide - A Different Way of Looking at SAS® Coding Richard Goldsmith, ASG, New York, NY ABSTRACT SAS data sets tend to be created wide, i.e. a single observation has many variables. This intuitive approach makes the most effective use of data storage space and allows the simplest approach to writing SAS code. 2017-02-13 · Run the SAS procedure, which uses the BY statement to specify each model. 1.

Sas long to wide array

As such, with PROC TRANSPOSE, we first have to use the procedure to transform the wide file into a longer file, and then use PROC TRANSPOSE, again, to transform the longer file into the ultimately desired width. 2018-04-03 2020-02-25 2011-01-31 set from long-to-wide and the complexity differs depending on whether one or more variables are involved. This paper compares three methods of long-to-wide conversion, two common (PROC TRANSPOSE and arrays) and one not commonly used (PROC SUMMARY). It also shows how PROC SQL can be used to find information Reshaping from long to wide in SAS can often be done using arrays or proc transpose. See our SAS arrays seminar and our reshaping in SAS learning module for details on these. However, reshaping pairs data from long to wide often means creating a second set of an unknown number of variables that are likely not named in any consistent or numbered manner. This tutorial explains how to reshape data by converting multiple variables from long format to wide format.

However, reshaping pairs data from long to wide often means creating a second set of an unknown number of variables that are likely not named in any consistent or numbered manner. This tutorial explains how to reshape data by converting multiple variables from long format to wide format. This tutorial explores 'Double Transpose' SAS method which is used to transpose multiple variables. It's a very handy technique to solve this challenge.

Example for your code would be something like: data new (keep = year var1-var3); set data; by year; array vars {3} var1-var3; retain var1-var3; if first.year then i=1; else i+1; vars{i} = faminc; if last.year then output; run; But I don't have SAS to double check this. Utilizing array processing allows you to reduce the amount of coding in the DATA step. Some may find that using array processing is confusing or even intimidating. First of all, the syntax for constructing arrays, especially for multi-dimensional arrays, is complicated; there are way too many rules. Once mastering syntax rules, you still need to 2018-05-07 · data tall; keep Employee_ID Qtr Amount; array numbers {4} qtr1-qtr4; set wide; do Qtr = 1 to 4; Amount=numbers {Qtr}; if Amount ne .
