simulprofiles: simulprofiles

In cghseg: Segmentation methods for array CGH analysis

Description

Simulates multiple CGH profiles

Usage

simulprofiles(M, n,k.mean,SNR,lambda)

Arguments

M	Number of profiles
n	length of profiles
k.mean	average number of segments per profile
SNR	Signal to Noise Ratio between the mean and the measurement noise. The mean of segments can take 3 values -1;0;0.58.
lambda	Variance ratio between measurement noise and bakground noise

Value

simul

list containing Y (dataframe of simulated CGH signals), Ki (the true number of segments per profile), mu0 (the true signal), theta0 (the true background intensity)
