Hill: Hill numbers

Description Usage Arguments Details Value Author(s) References See Also Examples

Description

Functions to compute Hill numbers. Hill computes the Hill number of a single q value. HillProfile computes Hill numbers for all elements in vector q.

Usage

1
2
Hill(w, q)
HillProfile(w, q = NULL)

Arguments

w

Vector of observed counts or frequencies.

q

Exponent.

Details

In Hill , only the first element in q is considered. HillProfile is vectorized and considers all elements in q.When q is NULL: in this case, a default vector is taken to obtain the full profile in the range, 0 to Inf.

Value

A value or vector of values corresponding to the Hill number estimators of passed exponents.
