This function takes a matrix of CGH data as the only argument and returns a crude estimate of the corresponding latent copy number states.
Matrix of aCGH data
Vector of threshold used to estimate the latent states
Given as argument a vector of threshold bounds the function simply applies the thresholding to the data and groups them into four subsets. Each subset is associated to a specific latent state.
Return a matrix of estimated latent states, that could be used as input of the main function.
