Conditional Weibull Distribution - Survival Table
Given that an item that has survived to an age of current_age, the cumulative probability of failure up to some future_time is given by:
β is the Weibull distribution shape parameter
η is the Weibull distribution characteristic life
See this related tool for calculating expected mean and median life using the conditional Weibull distribution.
Inputs #3 and #4 can either be a range (start, end, step) or a single value.
