sdf_rcauchy

Description

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

Arguments	Description
sc	A Spark connection.
n	Sample Size (default: 1000).
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”).
