Exploratory Data Analysis for a Multiple Plantation Forest Genetics Study Through a Simple Mean Polish Procedure

Many forest genetics studies were established over a broad area with many distinct plantations. Results from such a design can be easily explored by a procedure similar to "median polish." When the mean is used instead of the median, the procedure can yield a rich collection of information. Site effects, genetic effects and genetic by site interactions are arranged neatly in a two-way table. This provides the researcher some insight to conduct a further confirmatory data analysis and is specially useful for genotype stability studies. An outline of the mean polish procedure and illustrative examples based on a white ash multiplantation progeny test are given in this paper.
