R Package FrF2 for Creating and Analyzing Fractional Factorial 2-Level Designs
This article describes the R package FrF2 for design and analysis of experiments with 2-level factors. The package offers both regular and non-regular fractional factorial 2-level designs, in the regular case with blocking and split plot facilities and ...

Selection and determination of the effective factors on packaging paper print quality using design of experiments [PDF]
In present competitive world, packaging has a significant effect on the rate of sale. Unfortunately, in Iran's packaging industry, the variation of printing methods is too low which leads to reduction in quality of packing and the amount of sale ...

Augmenting 16-Run Two-Level Non-Regular Fractional Factorial Designs
When the resources for experimentation are limited, experimenters usually turn to the class of 2-level fractional factorial designs. Resolution III fractional factorial designs are the smallest available designs, but they alias main effects and 2-factor ...

R Package OBsMD for Follow-Up Designs in an Objective Bayesian Framework
Fractional factorial experiments often produce ambiguous results due to confounding among the factors; as a consequence more than one model is consistent with the data. Thus, the practical problem is how to choose additional runs in order to discriminate
