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 Life Distribution 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.
