IASC African Members Group presents:
Webinar on Response Surface Methodology with Application in R
Response surface methodology (RSM) is a collection of statistical and mathematical techniques useful for developing, improving, and optimizing processes. It also has important applications in the design, development, and formulation of new products, as well as in the improvement of existing product designs. The most extensive applications of RSM are in the industrial world, particularly in situations where several input variables potentially influence some performance measure or quality characteristic of the product or process. This performance measure or quality characteristic is called the response. It is typically measured on a continuous scale, although attribute responses, ranks, and sensory responses are not unusual. The RSM package for R provides several functions to facilitate classical response surface methods. The package is used to generate response surface designs, fit first and second order response surface models, make surface plots, obtain the path of steepest ascent, and do canonical analysis. The webinar will focus on generating an appropriate response surface design in R as well as using the software for fitting and displaying response surface models. It is envisaged that by the end of the webinar participants will have the requisite skills to undertake RSM analysis in R.
Speaker 1: Prof. John M. Mutiso
Prof. John M. Mutiso is a Professor of Statistics, School of Sciences & Aerospace Studies, Department of Mathematics, Physics and Computing, Moi University. He holds a PhD in Mathematics (Biostatistics) of Moi University, a Master of Science degree in Mathematical Statistics of University of Nairobi and a Bachelor of Education (Science) of University of Nairobi.
His research interest is on the construction of second and third order calculus optimum/unit value specific and sequential rotatable designs in both order and dimension from the six second order design classes comprising letter parameter
second order rotatable designs in three dimensions postulated in a paper by Draper, N. R. (1960b). Third order rotatable designs in three dimensions, Annals of Mathematical Statistics 31, 865-874 see pages 871-874 in particular for which
alphabetic optimality criteria are also being determined
