1Algorithms for accelerating the convergence of slow, monotone 2sequences from smooth, contraction mapping such as the EM algorithm. 3It can be used to accelerate any smooth, linearly convergent 4acceleration scheme. A tutorial style introduction to this package 5is available in a vignette on the CRAN download page or, when the 6package is loaded in an R session, with vignette("SQUAREM"). 7
