This data set contains 50 profiles corresponding to the density measurements of 50 0.5in-thick engineered woodboard, measured in 500 locations.
data("ss.data.wby")Format
A matrix with 500 rows (locations) and 50 columns (woodboard).
Source
Example 10.1 in the reference below. It is a variation of the one introduced by Walker (2002).
Details
This data set illustrates concepts in the book ``Quality Control with R''.
This data set should be used along with the ss.data.wbx data
set.
