summary.prop.RR: Summary for a prop.RR object

In prop.comb.RR: Analyzing Combination of Proportions and Relative Risk

Description

Provides results for an object of class prop.RR. It shows the contingency table with observed data, the parameter of interest and its estimated value. It provides confidence intervals (lower limit, upper limit) and p-values of the test (with z-values of statistics) for methods mentioned in references. It allows to calculate coverage probabilities for each method. It also indicates the alternative hypothesis and the recommendation about the optimal method for that particular case.

Usage

## S3 method for class 'prop.RR'
summary(object, ...)

Arguments

object	an object of class prop.RR.
...	Further arguments for summary.
