dist_data_cdf-methods: The data cumulative distribution function

In poweRlaw: Analysis of Heavy Tailed Distributions

The data cumulative distribution function

Description

This is generic function for distribution objects. This function calculates the data or empirical cdf.

The functions dist_data_all_cdf and dist_all_cdf are only available for discrete distributions. Their main purpose is to optimise the bootstrap procedure, where generating a vector xmin:xmax is very quick. Also, when bootstrapping very large values can be generated.

Usage

dist_all_cdf(m, lower_tail = TRUE, xmax = 1e+05)

dist_data_cdf(m, lower_tail = TRUE, xmax = 1e+05)

dist_data_all_cdf(m, lower_tail = TRUE, xmax = 1e+05)

## S4 method for signature 'discrete_distribution'
dist_data_cdf(m, lower_tail = TRUE, xmax = 1e+05)

## S4 method for signature 'discrete_distribution'
dist_data_all_cdf(m, lower_tail = TRUE, xmax = 1e+05)

## S4 method for signature 'ctn_distribution'
dist_data_cdf(m, lower_tail = TRUE, xmax = 1e+05)

Arguments

m	a distribution object.
lower_tail	logical; if TRUE (default), probabilities are P[X \le x], otherwise, P[X > x].
xmax	default 1e5. The maximum x value calculated when working out the CDF.

Note

This method does not alter the internal state of the distribution objects.
