R Dataset / Package MASS / stormer


On this Picostat.com statistics page, you will find information about the stormer data set which pertains to The Stormer Viscometer Data. The stormer data set is found in the MASS R package. You can load the stormer data set in R by issuing the following command at the console data("stormer"). This will load the data into a variable called stormer. If R says the stormer data set is not found, you can try installing the package by issuing this command install.packages("MASS") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the stormer R data set. The size of this file is about 335 bytes.

The Stormer Viscometer Data


The stormer viscometer measures the viscosity of a fluid by measuring the time taken for an inner cylinder in the mechanism to perform a fixed number of revolutions in response to an actuating weight. The viscometer is calibrated by measuring the time taken with varying weights while the mechanism is suspended in fluids of accurately known viscosity. The data comes from such a calibration, and theoretical considerations suggest a nonlinear relationship between time, weight and viscosity, of the form Time = (B1*Viscosity)/(Weight - B2) + E where B1 and B2 are unknown parameters to be estimated, and E is error.




The data frame contains the following components:


viscosity of fluid.


actuating weight.


time taken.
