Ssplitplot

Computing of a standard (simple) split-plot design analysis of variance.

This file computes the standard (simple) split-plot design analysis of variance, taking into account the linear model:
x_jkl = µ + a_j + ß_k + d_jk + Þ_l + (ßÞ)_kl + e_jkl
where j = 1,...,a (blocks); k = 1,...,b (factor 1); l = 1,...,c (factor 2); d_jk ~ N[0,var_d] (error main plots); e_jkl ~ N[0,var_e] (error sub-plots).
It needs to input the data matrix (size of matrix must be n-by-4; data=column 1, block=column 2,factor 1=column 3, factor 2=column 4)[in some another notations the blocks source also is known as the replicates], and the significance level (default = 0.05).
It outputs a complete analysis of variance table.
