Generating a league table
A league table is generated for all possible pairs of the treatments. The league table can be outputted as a CSV file through setting out.csv="filename".
nmaleague(x, method="NH", eform=FALSE, digits=3, PI=FALSE, out.csv=NULL)
x: Output object of setupmethod: Estimation and prediction method. NH: Noma-Hamura's improved REML-based methods (default). REML: The ordinary REML method.eform: A logical value that specify whether the outcome should be transformed by exponential function (default: FALSE)digits: Number of decimal placesPI: A logical value that specify whether the inference or prediction results are providedout.csv: A character object that specify a filename if the user wants to output the league table as a CSV file (e.g., out.csv="out_league.csv").A league table is generated.
