2020-3-1 · The rest of the paper is organized as follows. In Section 2, we present the explicit problem formulation, and establish the optimality of Design B in estimating σ 2.Under various common distributions, theoretical values of Var (σ ˆ 2) have been evaluated for both Designs A and B. It is shown that Design B achieves a substantially less dispersed σ ˆ 2 than Design A. Section 3 presents the ...

Experimental Design and Analysis of Variance -

2018-1-1 · Screening Study. Plackett–Burman design is used for the screening study to calculate the different factors and parameters affecting encapsulation efficiency of peptide and proteins (Shaki et al., 2014, Guerreo-Ochoa et al., 2015). The experimental factors will be investigated through a design matrix of experiments using a simple linear model Eq.

2020-6-12 · The lack of locally validated screening instruments contributes to poor detection of depression in primary care. The Patient Health Questionnaire-9 (PHQ-9) is a brief and freely available screening tool which was developed for primary care settings; however, its accuracy may be affected by the population in which it is administered. This study aimed to determine the validity and reliability of ...

Definitive screening design (DSD), a novel 3-level multivariate analysis approach (MVA), was used for screening the investigated variables. Contrary to the traditional UVA approach, the MVA studies the influence of the detached factors while reducing the effort and resources required by executing the lowest possible number of experimentations.
