dat3sample: dat3sample

In VBmix: Variational Bayesian Mixture Models

Description

generates data elements according to SYN3 process (sample along a 2D circle with additive noise, and linearly transform to higher dimensional space with further noise addition, see reference).

Usage

dat3sample(nelts, radius, noise, transform=generate2Dtransform(2), 
	oldbounds = NULL, newbounds = NULL)

Arguments

nelts	number of elements to generate.
radius	radius of the sphere to sample from.
noise	additive noise magnitude.
transform	matrix defining linear transform. Defaults to I.
oldbounds	optional argument for sample rescaling. If not NULL, transmitted to setDomain as oldspan.
newbounds	optional argument for sample rescaling. If not NULL, transmitted to setDomain as newspan.

Value

matrix of sampled row-elements.
