Abstract
In this study we discuss multiple comparison procedures for checking differences among a sequence of normal means with ordered restriction. Lee and Spurrier (1995) proposed a single step multiple comparison procedure checking difference between adjacent two means. There exists two kinds of stepwise multiple comparison procedures developing Lee and Spurrier (1995). Shiraishi (2014) proposed a step down multiple comparison procedure based on closed testing procedure. Douke et al. (2006) proposed a sequentially rejective multiple comparison procedure. In this study we propose a step up multiple comparison procedure developing Lee and Spurrier (1995). We give numerical results regarding critical values for a specified significance level and power of the test intended to compare single step procedure and three kinds of stepwise procedures.
