Re. Victorbabu 1 Department of Statics, Acharya Nagarajuna University, GUNTUR - 522 510 (A.P.). INDIA <p style="text-align: justify;">In this paper, a new method of construction of modified second order slope rotatable designs with equi-spaced levels using pairwise balanced designs is suggested. The proposed method may sometimes lead to designs with less number of design points than those available in the literature. A table is provided where for a range of different values of v (v-stands for number of factors) the design points needed by different methods are compared for <img src="file:///D:/atif/Drive%20E%20data/desktop%20data/Business/journal/JUSPS%20A&B/JUSPS/20(2)/AbstWMF0.JPG" style="height:10px; width:46px" />.<br />  </p> https://ultraphysicalsciences.org/paper/1296/ Second order response surface designs equi-spaced doses designs, modified second order slope rotatable designs
