[R] analysis of variance using lmer

2009-02-26 Thread Lars Kunert
Hi, I am trying to do an analysis of variance for an unbalanced design. As a toy example, I use a dataset presented by K. Hinkelmann and O. Kempthorne in "Design and Anaylysis of Experiments" (p353-356). This example is very similar to my own dataset, with one difference: it is balanced. Thus it is

This is a follow-up mail of "the effect of blocking on the size of confidence intervals - analysis using aov". In both mails I pursue the idea of using blocking factors in order to reduce the width of confidence intervals. My dataset comprises, a quantitative response variable, namely: "response"

Hi, I am a method developer in drug discovery. I have developed a similarity searching method for small (drug-like) molecules. I want to compare the performance of my method to the performance of other methods. Similarity searching methods are commonly assessed by their ability to (re)discover a s
