In this paper we initiate the study of optimality in nested row column setting and establish, under the usual fixed effects model, optimality of certain non-binary nested designs which have not ...

Block designs with nested rows and columns are introduced. These designs are a generalization of lattice square designs. A procedure for analysis of these designs is given. Balanced designs are ...

Messy Excel formulas are more than just an eyesore—they're harder to maintain. Every repeated cell reference and tangled parenthesis makes your work difficult to audit, edit, and share. That's why you ...
