CHANGES IN VERSION 2.0.0
------------------------
NEW FEATURES
o spfabia: fabia for a sparse data matrix (in sparse matrix
format) and sparse vector/matrix computations in the code
to speed up computations.
spfabia applications:
(a) detecting >identity by descent< in next generation
sequencing data with rare variants,
(b) detecting >shared haplotypes< in disease studies based
on next generation sequencing data with rare variants
o fabia for non-negative factorization (parameter: non_negative)
o changed to C and removed dependencies to Rcpp
o improved update for lambda (alpha should be smaller, e.g. 0.03)
o introduced maximal number of row elements (lL)
o introduced cycle bL when upper bounds nL or lL are effective
o reduced computational complexity
BUG FIXES
o update formula for lambda: tighter approximation
o corrected inverse of the conditional covariance matrix of z
CHANGES IN VERSION 1.4.0
------------------------
NEW FEATURES
o introduced maximal number of row elements (nL)
BUG FIXES
o single or no bicluster
o zero elements in biclusters
