cloud {Rnotes} | R Documentation |
The cloud point of a liquid is a measure of the degree of crystalization in a stock that can be measured by the refractive index. It has been suggested that the percentage of I8 in the base stock is an excellent predictor of cloud point using the second or third order polynomial.
The data in the cloud
data frame were collected on stocks with known
percentage of I8. The components are as follows
item{Ispc}{
The known percentage of I8.
}
item{Cloudpt}{
The cloud point measurement.
}
Polynomial regression. Simple plots.
