Two versions to support how you analyze data obtained from quantitative accelerated life tests

Accelerated Life Testing - Standard

This version is intended to be an entry-level tool for the reliability professional interested in basic quantitative accelerated life testing data analysis applications.

Accelerated Life Testing - PRO

This version provides advanced capabilities made possible by extensive research and development in complex quantitative accelerated life testing data analysis techniques.

	Standard	PRO
Life Distributions	Both versions support Weibull, lognormal and exponential.
Life-Stress Relationships	Arrhenius Eyring Inverse Power Law Temp-Humidity Temp-Nonthermal	All of the ALTA Standard models plus: Generalized Eyring Proportional Hazards Generalized Log-Linear (with user-defined transformations for creating models with up to eight simultaneous stresses) Cumulative Damage (with the option to analyze multiple time-dependent stresses)
Parameter Estimation	Both versions provide Maximum Likelihood Estimation (MLE).
Stresses	Provides models that can analyze data with 1 or 2 stresses that do not vary with time.	Provides models that can analyze data with up to 8 stresses that may vary with time. Provides a utility to define and manage stress profiles. Use level stress can also be specified to vary with time.
Confidence Intervals	Both versions provide confidence intervals on calculated results and plots.
Analyze data with indicator variables (stress is on/off, lot, etc.)	No	Yes
Monte Carlo Data Generation	Available for supported models only.	Available for all models, including those with multiple and/or time-dependent stresses.
Accelerated Test Plan Utility	Both versions provide access to the accelerated test planning utility.

Weibull++'s Accelerated Life Testing module is the best package I've seen for accelerated life testing.
