randGauss function
The randGauss function returns a normally distributed random column with the specified number of elements. If the number of elements is specified, a random column with n (=number of rows) elements is created.
Parameters
randGauss(n, seed, mean, stddev)
Parameter | Description |
|---|---|
n | The number of rows to fill with random values. Its default value corresponds to the number of rows of the dataset. |
seed | A base value, used to generate random values. It makes the random generation deterministic. |
mean | 0 as default, it is the normal distribution’s mean. |
stddev | 1 as default, it is the normal distribution’s standard deviation. |
Example
The following example uses the Students Performance dataset.
This example isn’t based on a real scenario, it only explains how to use the function.

|---|---|
In this example, we want to add a new column and to fill the first 20 rows with a seed of 2, using the randGauss function. Add a new column and type the following formula: No mean and stddev have been specified. |  |
