Create a Random Sample in SAS with PROC SQL Generate a Random Sample Based on a Fixed Number of Observations Generate a Random Sample Based on a Fixed Percentage of Observations 2. The inclusion or exclusion criteria appear after the IF statement. The table arranges the variables alphabetically or numerically by increasing value. If you omit this statement, the program generates a different series of random numbers every time you run it. The SAS dataset uses two data types: numeric and character. If you just want to DOUBLE the number of observations then just use two output statements. The table consists of three rows and three columns, namely a character column, a numeric column, and a SAS date column. Or read the input dataset twice. SAS vs. SQL SYNTAX PROC SQL; SELECT column (s) FROM table (s) | view (s) WHERE expression Your input dataset does not appear to have the count of the number of rows per ID value. The third method to add a row to a dataset in SAS is with PROC APPEND. The first few rows of output should look like this: You should see that the column containing the cases for State appears completely empty, indicating that all the cases in this dataset have missing observations for State. If you had that variable (call it NREPS) then your DO loop to output replicates would be simple. You don't show what the table with the commission information actually looks like.

In this tutorial, we use the following terms to refer to these two tasks: A subset is selection of cases taken from a dataset that match certain criteria. The general code above only shows the case where a dataset is partitioned into two datasets, but it's possible to partition a dataset into as many pieces as you wish. A split acts as a partition of a dataset: it separates the cases in a dataset into two or more new datasets. So, it is always necessary to create a table with the rows you want to add beforehand.
