Design and Analysis of Fractional Factorial Experiments From the Viewpoint of Computational Algebraic Statistics [PDF]
Journal of Statistical Theory and Practice, 2012 We give an expository review of applications of computational algebraic statistics to design and analysis of fractional factorial experiments based on our recent works. For the purpose of design, the techniques of Gr bner bases and indicator functions allow us to treat fractional factorial designs without distinction between regular designs and non ...

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

Weighted rank statistics in factorial designs with fixed effects
Statistica Neerlandica, 2002 Nonparametric methods for the analysis of factorial designs with two fixed factors are considered. The sample sizes may be unequal and the distribution functions are not assumed to be continuous. Nonparametric hypotheses for the main effects and for the interaction are tested by ranking procedures where the statistics are weighted according to the ...

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.

Statistical optimization of dithranol-loaded solid lipid nanoparticles using factorial design [PDF]
Brazilian Journal of Pharmaceutical Sciences, 2011 This study describes a 3² full factorial experimental design to optimize the formulation of dithranol (DTH) loaded solid lipid nanoparticles (SLN) by the pre-emulsion ultrasonication method. The variables drug: lipid ratio and sonication time were studied at three levels and arranged in a 3² factorial design to study the influence on the response ...
