Question 8.2 Suppose that in Problem 6.15, only a one-half fraction of the 2^4 design could be run. Construct the design and perform the analysis, using the data from replicate I. Since in this case we have to run a one-half fraction of the design so we’ll be running a 2^(4-1) design where K=4 and P=1. Our defining relationship is I = ABCD in...

FA 16 In a process development study on yield, four factors were studied, each at two levels: time (A), concentration (B), pressure (C), and temperature (D). Part A: a) Display the halfnormal plot for this data and determine which factors appear to be significant. library(DoE.base) A <- c(-1,1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,1) B <- c(-1,-1...

The effect of five different ingredients (A, B, C, D, E) on the reaction time of a chemical process is being studied. Each batch of new material is only large enough to permit five runs to be made. Furthermore, each run requires approximately 1.5 hours, so only five runs can be made in one day. The experimenter decides to run the experiment as a ...
