Checks a trial for the spatial structure the\nsizing methods assume (semivariogram, Moran's I, kriged field\nmap), summarises the coefficient of variation over every plot\nshape the grid admits, and estimates the optimal plot size by\nthe modified maximum curvature method of Meier and Lessman\n(1971), by the linear response plateau (LRP) and quadratic\nresponse plateau (QRP) models, and by the closed form of\nParanaiba, Ferreira and Morais (2009), which can be compared\nside by side. From the coefficient of variation at the optimum\nit derives the number of replications needed to detect a given\ndifference between treatment means, as in Cargnelutti Filho and\nothers (2014). Every method returns standardised diagnostic\nstatistics, optional bootstrap uncertainty for the breakpoint,\nand publication-style plots.", "License": "GPL (>= 3)", "URL":
