Hill {QSutils} | R Documentation |
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
.
Hill(w, q) HillProfile(w, q = NULL)
w |
Vector of observed counts or frequencies. |
q |
Exponent. |
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.
A value or vector of values corresponding to the Hill number estimators of passed exponents.
