Methods for individual participant data meta-analysis of survival outcomes commonly focus on the hazard ratio as a measure of treatment effect. Recently, Siannis et al. (2010, Statistics in Medicine 29:3030-3045) proposed the use of percentile ratios as an alternative to hazard ratios. We describe a novel two-stage method for the meta-analysis of percentile ratios that avoids distributional ass...

In an recent paper [1], DeGroat and Roberts developed a re-orthogonalization scheme for stabilizing eigenstructure updating algorithms. In this note, we show that only part of this scheme, namely the re-normalization, is essential for the stability, so that a cheaper scheme –with roughly half as many computations– can perform equally well.
