new_quantile {scpoisson}

A more "continuous" approximation of quantiles of samples with a few integer case

Description

This function returns a data frame including data points and corresponding quantile.

Usage

new_quantile(data, sample)

Arguments

data

A numeric vector of sampled data points.

sample

A character string denotes which sample data points come from.

Details

This is a function developed to get quantile for samples with only a few integer values. Define both p_{-1} = 0 and q_{-1} = 0. Replace the point mass at each integer z by a bar on the interval [z – \frac{1}{2}, z+ \frac{1}{2}] with height P(X = z). This is a more "continuous" approximation of quantiles in this case.

Value

A data frame contains the corresponding probability from cumulative distribution function (CDF), sample name, and corresponding respective quantiles.
