Algorithms for accelerating the convergence of slow,
monotone sequences from smooth, contraction mapping such as the
EM algorithm. It can be used to accelerate any smooth, linearly
convergent acceleration scheme. A tutorial style introduction
to this package is available in a vignette on the CRAN download
page or, when the package is loaded in an R session, with
vignette("SQUAREM").
