Accelerating the quadratic lower-bound algorithm via optimizing the shrinkage parameter

Tian, Guo-Liang; Tang, Man-Lai; Liu, Chunling - In: Computational Statistics & Data Analysis 56 (2012) 2, pp. 255-265

When the Newton–Raphson algorithm or the Fisher scoring algorithm does not work and the EM-type algorithms are not … available, the quadratic lower-bound (QLB) algorithm may be a useful optimization tool. However, like all EM-type algorithms …
