Design of Experiments (DoE) applied to Pharmaceutical and Analytical Quality by Design (QbD)

open access: yesBrazilian Journal of Pharmaceutical Sciences, 2018
According to Quality by Design (QbD) concept, quality should be built into product/method during pharmaceutical/analytical development. Usually, there are many input factors that may affect quality of product and methods. Recently, Design of Experiments (

On comparing the prediction variances of some central composite designs in spherical regions: a review

open access: yesStatistica, 2013
Three second-order response surface designs, namely: central composite design, small composite design and minimum-run resolution V design are compared for factors 3 to 7 in spherical regions using the G- and I- optimality criteria.
