Generalizations of the Tests by Kruskal-Wallis, Friedman and van der Waerden for Split-plot Designs
Austrian Journal of Statistics, 2023 Generalizations of the 1-factorial tests by Kruskal-Wallis and Friedman, as well as of the van der Waerden test are proposed for factorial split-plot designs, both allowing interactions.

Efficient Blocked Fractional Factorial Designs for Stated Choice Experiments of Size Two and Four
International Journal of Mathematics and Mathematical Sciences, 2023 Stated choice experiments are increasingly becoming popular due to their ability to optimize information gain with limited resources. Many designs have been developed for the selection of various attributes and their levels to form choice sets.

Analysis of frequency data: The ANOFA framework [PDF]
Tutorials in Quantitative Methods for Psychology, 2023 Analyses of frequencies are commonly done using a chi-square test. This test, derived from a normal approximation, is deemed generally efficient (controlling type-I error rates fairly well and having good statistical power).

NRC Designs—New Tools for Successful Agricultural Experiments
Agronomy, 2021 In a nested row–column design (NRC), the experimental units in each of n blocks are grouped into n1 rows and n2 columns. Due to its structure, this experimental design allows full control of the experimental material and a relatively simple feedback loop

D-Optimal Designs for Binary and Weighted Linear Regression Models: One Design Variable
Mathematics, 2023 D-optimality is a well-known concept in experimental design that seeks to select an optimal set of design points to estimate the unknown parameters of a statistical model with a minimum variance.

QANOVA: quantile-based permutation methods for general factorial designs [PDF]
Test (Madrid), 2019 Population means and standard deviations are the most common estimands to quantify effects in factorial layouts. In fact, most statistical procedures in such designs are built toward inferring means or contrasts thereof.
