Abstract

In statistical books for the analysis of designed experiments one can finds sometimes also the computation of the number of replications for balanced one-factor and two-factors designs. Later there were papers published concerning the computation of the number of replications of at most three-factors crossed or nested balanced designs. In 2011 the book “Optimal experimental design with R” was published; further a special R- program OPDOE was made to do the computation for these designs and the OPDOE program was used in this book. In this paper an extension of the determination of the minimum number of replications for balanced designs is given for four-factor crossed designs. The balanced cross classification of the four-way analysis of variance of the following models are investigated: Model 1 The factors A, B, C and D are all fixed; Model 2 D is random A, B and C are fixed; Model 3 C and D are random, A and B are fixed; Model 4 B, C and D are random, A is fixed. For these models small R-programs are given to compute the minimal number of the replications for testing the fixed effects using the non-centrality parameter λ of the non-central F- distribution F(df1, df2, λ). Further balanced Split-Plot design with one or two fixed factors in the main-plots are considered. The Blocks are denoted with B. The F statistics for testing the significance of the fixed factors are described and small R-programs for the determination of the minimal number of replications are given using the non-centrality parameter λ of the non-central F- distribution F(df1, df2, λ).
