Apply the Entropy Concentration Theorem
Description
The Entropy Concentration Theorem (ECT; Edwin, 1982) states that if is large enough, then
% of all
and
is determined by the upper tail are
of a
distribution, with
(which equals
in a surrogate evaluation context).
Usage
ECT(Perc=.95, H_Max, N)
Arguments
Perc |
The desired interval. E.g., |
H_Max |
The maximum entropy value. In the binary-binary setting, this can be computed using the function |
N |
The sample size. |
Value
An object of class ECT
with components,
Lower_H |
The lower bound of the requested interval. |
Upper_H |
The upper bound of the requested interval, which equals |
