In many cases accelerated reliability test conducted under more than one accelerated condition simultaneously: temperature, voltage, humidity and etc.
Currently it is possible to use only one accelerated condition in Fit Life by X platform in JMP, used for assessment of accelerated reliability test parameters.
Please consider to add more than one X variable to Fit Life by X platform.
Such option is already implemented in Minitab software, see below screenshot of Fit Life by X platform in JMP and Accelerated Life Testing platform in Minitab side by side.
