DSD_Target: Target Data Stream Generator

Description

A data stream generator that generates a data stream in the shape of a target. It has a single Gaussian cluster in the center and a ring that surrounds it.

Usage

DSD_Target(
  center_sd = 0.05,
  center_weight = 0.5,
  ring_r = 0.2,
  ring_sd = 0.02,
  noise = 0
)

Value

Returns a DSD_Target object.

Arguments

center_sd

standard deviation of center

center_weight

proportion of points in center

ring_r

average ring radius

ring_sd

standard deviation of ring radius

noise

proportion of noise
