whereY is thepredicted response (De in this case),Xi is theun-codedor codedvalues of the
factors (FeCl3concentrationdenotedbyA,%alcohol towater ratio isdenotedbyBandtime is
denoted by C), βo and βi are constant and γ is the surface tension of alcohol used. The
corresponding responsemodel for the obtained aspect ratio of the particles,which are valid
forun-coded factor, is:

Linear regression can beused to obtain corresponding values of βi.Figure 3presents typical
comparisonofexperimentalandpredictedvaluesusingdifferentβivalues. It canbeseen from
Figure3 that thecomparisonbetweenexperimental andpredictedvaluesagreesverywell.
