cdf: Function to compute the cumulative distribution of a variable

Description

Builds the cumulative distribution of a vector, using a step% of the data as fixed-intervals.

Usage

cdf(y = y, step = 0.05)

Value

returns a dataframe having two columns: the first contains the random variable values and the second the cumulative distribution for the variable.

Arguments

y

a vector of a random variable

step

a numeric proportion of the data used as increment interval for building the cdf of the random variable. The default value for 'step' is 0.05, representing a 5%.
