Life Distribution

Fit Distributions to Lifetime Data

The Life Distribution platform models time-to-event data. The platform accommodates both right-censored and interval-censored data.

Use the Life Distribution platform to do the following:

• Compare multiple distributional fits to determine which distribution best fits your data.

• Construct Bayesian fits.

• Model zero-failure data.

• Compare groups to analyze group differences.

• Analyze multiple causes of failure.

• Estimate the components of a mixture and estimate the probability that an observation comes from a given component.

• Estimate the components of a competing risk mixture and estimate the impact of a component on an observation.
