Wool data


This is a three-factor experiment with each factor at three levels, for a total of 27 runs. Samples of worsted yarn were with different levels of the three factors were given a cyclic load until the sample failed. The goal is to understand how cycles to failure depends on the factors.




This data frame contains the following columns:


length of specimen (250, 300, 350 mm)


amplitude of loading cycle (8, 9, 10 min)


load (40, 45, 50g)


number of cycles until failure
