The Refdist Method for Design and Analysis of Plant Trials (30b39598-3af1-49ef-a180-527304532563)

Refdist is a simple but valid approach to planning or analyzing a test-vs-control plant trial that uses accumulated plant performance data to calculate objective criteria for judging the trial outcome. Refdist calculations and results are explained and illustrated with data typical of the mining industry. Findings from a simulation study of Refdist statistical properties are reported. Suggestions for dealing with messy data situations are offered.
