Blon.val {BeyondBenford}R Documentation

Blondeau Da Silva's values

Description

The function returns Blondeau Da Silva's probability that a figure is at a given position (once the associated lower and upper bounds have been specified) and, if requested, the associated standard deviation.

Usage

Blon.val(lwbound = 10^(dig - 1), upbound, fig, dig = 1, sd = 0)

Arguments

lwbound

A positive integer, which characterizes the data. All (or most) of the data are greater than this "lower bound".

upbound

A positive integer, which characterizes the data. All (or most) of the data are lower than this "upper bound".

fig

The considered figure.

dig

The chosen position of the digit (from the left).

sd

If sd=0, only the probability is returned. Else, the function returns a dataframe containing the probability and the standard deviation of the expected digit frequency.

Value

The function returns Blondeau Da Silva's probability and, if requested, its standard deviation.
