 +Under the semi-parametric linear regression model with right-censored
 +data,   the Buckley-James  estimator (BJE)   of the parameter was proposed in (1979) and
 +is the standard extension of the least squares estimator.
 + Buckley and James proposed an iterative algorithm and is currently implemented in R package.
 +But their algorithm often does not lead to an estimate even though the BJE exists.
 +Yu and Wong (2002) proposed a non-iterative algorithm and it can find all possible
 +BJEs. That algorithm is improved in this paper.
