Regression and the hypothesis of accelerated life

T. Paul Hutchinson

Research output: Contribution to journalArticle


Experiments on accelerated aging assume that curves of performance (vertical axis) versus logarithm of time (horizontal axis) are parallel in different conditions (eg temperatures), in the sense of being a constant horizontal distance apart. It is shown how multiple regression may be adapted to the estimation of the horizontal shifts, which can then be related to objective measures of the conditions.
