conf: Visualization and Analysis of Statistical Measures of Confidence

Description

Enables:

1. confidence region plots in two-dimensions corresponding to a user given dataset, level of significance, and parametric probability distribution (supported distribution suffixes: cauchy, gamma, invgauss, lnorm, llogis, logis, norm, unif, weibull),

2. coverage simulations (if a point of interest is within or outside of a confidence region boundary) for either random samples drawn from a user-specified parametric distribution or for a user-specified dataset and point of interest,

3. calculating confidence intervals and the associated actual coverage for binomial proportions, and

4. calculating the support values and the probability mass function of the Kaplan-Meier product-limit estimator.

5. plotting the actual coverage function for a randomly right-censored data set with exponential failure times and exponential censoring times.
