discr.sims.fat_tails {mgc}

Discriminability Spread Simulation

Description

A function to simulate data with the same mean that spreads as class id increases.

Usage

discr.sims.fat_tails(
  n,
  d,
  K,
  signal.scale = 1,
  rotate = FALSE,
  class.equal = TRUE,
  ind = FALSE
)

Arguments

n

the number of samples.

d

the number of dimensions.

K

the number of classes in the dataset.

signal.scale

the scaling for the signal dimension. Defaults to 1.

rotate

whether to apply a random rotation. Defaults to TRUE.

class.equal

whether the number of samples/class should be equal, with each class having a prior of 1/K, or inequal, in which each class obtains a prior of k/sum(K) for k=1:K. Defaults to TRUE.

ind

whether to sample x and y independently. Defaults to FALSE.
