Description

Generate a random dataset shaped like a parabol and a gaussian distribution

Usage

data.parabol(
  n = c(500, 100),
  xlim = c(-3, 3),
  center = c(0, 4),
  coeff = 0.5,
  sigma = c(0.5, 0.5),
  levels = NULL,
  graph = TRUE,
  seed = NULL
)

Arguments

Number of observations in each class.

xlim

Minimum and maximum on the x axis.

center

Coordinates of the center of the gaussian distribution.

coeff

Coefficient of the parabol.

sigma

Variance in each class.

levels
