Generate random samples from a geometric distribution




Generator method for creating a single-column Spark dataframes comprised of i.i.d. samples from a geometric distribution.


sdf_rgeom(sc, n, prob, num_partitions = NULL, seed = NULL, output_col = "x") 


Arguments Description
sc A Spark connection.
n Sample Size (default: 1000).
prob Probability of success in each trial.
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”).
