sdf_rlnorm
Description
Generator method for creating a single-column Spark dataframes comprised of i.i.d. samples from a log normal distribution.
Usage
sdf_rlnorm(
sc,
n,
meanlog = 0,
sdlog = 1,
num_partitions = NULL,
seed = NULL,
output_col = "x"
) Arguments
| Arguments | Description |
|---|---|
| sc | A Spark connection. |
| n | Sample Size (default: 1000). |
| meanlog | The mean of the normally distributed natural logarithm of this distribution. |
| sdlog | The Standard deviation of the normally distributed natural logarithm of this distribution. |
| num_partitions | Number of partitions in the resulting Spark dataframe (default: default parallelism of the Spark cluster). |
| seed | Random seed (default: a random long integer). |
| output_col | Name of the output column containing sample values (default: “x”). |
