Compute 3x3 moving averages
Fertility Classes heatmap with 3 * 3 moving average values ---
Fit Fairfield-Smith's variance law to matrix data with ggplot2 plots
Generate valid plot sizes and shapes
Compute T values (sum of block totals) for a given h x w plot
Make a horizontal vector from a matrix
Make a vertical vector from a matrix
Compute population variance for given h x w plot
Compute first-order serial correlation of a vector
computes the first-order serial correlation for both directions.
Provides methods for determining optimum plot size and shape in field experiments using Fairfield-Smith's variance law approach. It will evaluate field variability, determine optimum plot size and shape and study fertility trends across the field.
