discr.sims.cross: Discriminability Cross Simulation

In mgc: Multiscale Graph Correlation

Description

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

Usage

discr.sims.cross(
  n,
  d,
  K,
  signal.scale = 10,
  non.scale = 1,
  mean.scale = 0,
  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 10.
non.scale	the scaling for the non-signal dimensions. Defaults to 1.
mean.scale	whether the magnitude of the difference in the means between the two classes. If a mean scale is requested, d should be at least > K.
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.
