dat2sample: dat2sample

In VBmix: Variational Bayesian Mixture Models

Description

generates data elements according to SYN2 process (sample along a semi-sphere with additive noise, see reference).

Usage

dat2sample(nelts, radius, noise, oldbounds = NULL, newbounds = NULL)

Arguments

nelts	number of elements to generate.
radius	radius of the sphere to sample from.
noise	additive noise magnitude.
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.
