Arguments
Y
A n*m matrix,in the multiple copy number variation detection problem,n denotes #(n) samples,while m denotes #(m) probs.
X
A n*m matrix,original estimator of Y,give X as the same size of Y,often let X=Y.
D
A n*m matrix,original direction in BCGD algorithm.
lambda1
A real number larger than 0,the first penalty used in the model,controls the overall
copy number alteration amount of the target chromosome.
lambda2
A real number larger than 0,the second penalty used in the model,controls the frequency
of the alterations in the target region.
alpha
Original alpha used in the first step.
