bpcp:Beta Product Confidence Procedure for Right Censored Data
Calculates nonparametric pointwise confidence intervals for the survival distribution for right censored data, and for
medians [Fay and Brittain <DOI:10.1002/sim.6905>]. Has
two-sample tests for dissimilarity (e.g., difference, ratio or
odds ratio) in survival at a fixed time, and differences in
medians [Fay, Proschan, and Brittain <DOI:10.1111/biom.12231>].
Basically, the package gives exact inference methods for one-
and two-sample exact inferences for Kaplan-Meier curves (e.g.,
generalizing Fisher's exact test to allow for right censoring),
which are especially important for latter parts of the survival
curve, small sample sizes or heavily censored data. Includes
mid-p options.
