Zipf( <Number of Elements>, <Exponent> )
Returns a bar graph of a Zipf distribution.
Parameters:
Number of Elements: number of elements whose rank we study
Exponent: exponent characterizing the distribution
Zipf( <Number of Elements>, <Exponent> , <Boolean Cumulative> )
Returns a bar graph of a Zipf distribution when Cumulative = false.
Returns a graph of a cumulative Zipf distribution when Cumulative = true.
First two parameters are same as above.
Zipf( <Number of Elements>, <Exponent> , <Variable Value v>, <Boolean Cumulative> )
Let X be a Zipf random variable.
Returns P( X = v) when Cumulative = false.
Returns P( X ≤ v) when Cumulative = true.
First two parameters are same as above.
Example: Zipf(10, 1 , 5, false) yields 0.07 in the Menu view algebra.svg Algebra View and \mathrm{\mathsf{ \frac{504}{7381} }} in the Menu view cas.svg CAS View.
