Creation of a large synthetic dataset

The script uses a DATA STEP to create the `myLib.biggerDataset` dataset. A DO loop is employed to iterate over an extended range of values. The variable `i` is initialized with a missing value, then iterates from -1,000,000 to 1,000,000. For each iteration, the variable `j` is created by converting the numeric value of `i` into a character string using the PUT function and the `fmtNum.` format. The variable `k` is assigned a pseudo-random uniformly distributed numeric value generated by the `RANUNI(17)` function. Each iteration writes a new observation to the dataset.

Data Analysis

Type : INTERNAL_CREATION

The `myLib.biggerDataset` dataset is entirely created internally within the script via a DATA STEP. The values for variables `i`, `j`, and `k` are generated by a DO loop, the PUT function for format conversion, and the RANUNI function for random number generation.

DATA STEP Data

Explanation :
This DATA STEP initiates the creation of the `myLib.biggerDataset` dataset. The `DO i = ., -1e6 to 1e6` loop generates values for `i` ranging from 'missing' to -1,000,000 up to 1,000,000. `j` is a character version of `i`, and `k` is a random number. `OUTPUT` writes each observation.
