For example,the fatigue strength distribution of some materials may be reasonably represented usinga lognormal distribution, in which case the logarithm of stress values would be normallydistributed.

Suppressingthe intercept in the FIXONE or FIXONETIME case merely changes the name of the intercept toa fi[r]
