Generator method for creating a single-column Spark dataframes comprised of i.i.d. samples from a Cauchy distribution.
Usage
sdf_rcauchy(
sc,
n,
location = 0,
scale = 1,
num_partitions = NULL,
seed = NULL,
output_col = "x"
)Arguments
- sc

- location
Location parameter of the distribution.
- scale
Scale parameter of the 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").
