Another Look at Among and Within Class Regressions in Analysis of Covariance
نویسنده
چکیده
In a recent paper, Monlezun and Blouin (1988) proposed an analysis of covariance for a split plot experiment. They suggest a model consisting of five regression coefficients, one for each of the effects whole-plot treatment means, whole-plot errors, split plot-treatment means, whole-plot and split-plot treatment interactions and the experimental errors. In this paper we critically examine the analysis suggested by Monlezun and Blouin (1988). We relate their analysis to the within class (internal) and among class (external) regressions considered by Wishart and Sanders (1934) and Smith (1957) and present some of the issues that are not usually addressed in text books.

The Pardoner of the Tales is ...
