| Abstract: | Two nonparametric Approaches(Linear estimator and Minimum distance estimator) of accelerated life testing with competing causes of failure are presented by deleting the requirement that the common parametric family of life distributions under all the stresses be specifiesd in advance. the requirement that the time transformation function be specified is relained. |

| Keywords: | competing causes of failure accelerated life test nonparametric estimation least square estimation least distance estimation |
