quantile.disagree.sim: S3 method for class 'disagree.sim'

Description

Provides a concise quantile summary of objects created using the function ad.m.sim. The simulation functions for the average deviation of the mean (or median) return a limited number of estimated values. Consequently, the normal quantile methods are biased. The quantile methods incorporated in this function produce unbiased estimates.

Usage

# S3 method for disagree.sim
quantile(x,confint,…)

Arguments

x

An object of class 'disagree.sim'.

confint

The confidence intervals to return. The values of 0.05 and 0.01 return the approximate 5 percent and 1 percent confidence intervals. Values equal to or smaller than these values are significant (p=.05, p=.01).

…

Optional arguments. None used.

Value

A dataframe with two columns. The first column contains the quantile value and the second contains the estimate based on the object.
