Experimental Design and Analysis for Tree Improvement
by Emlyn Williams, Chris Harwood, Colin Matheson
This third edition of Experimental Design and Analysis for Tree Improvement provides a set of practical procedures to follow when planning, designing and analysing tree improvement trials. Using many fully worked examples, it outlines how to: design field, glasshouse and laboratory trials; efficiently collect and construct electronic data files; pre-process data, screening for data quality and outliers; analyse data from single and across-site trials; and interpret the results from statistical analyses. The authors address the many practical issues often faced in forest tree improvement trials and describe techniques that will efficiently give conclusive results. The techniques provided are applicable to the improvement of not only trees, but to crops in general. Building on the success of the second edition, this new edition has been fully revised to include the construction of p-rep and spatial designs using the commercially available software package for design generation (CycDesigN). For analysis of the examples, it provides online Genstat and SAS programs and a link to R programs.
