- statistics: [nlogL, avar] = explike (param, data)
Compute the negative log-likelihood of data under the exponential
distribution with given parameter value.
Arguments
-
param is a scalar containing the scale parameter of the exponential
distribution (equal to its mean).
-
data is the vector of given values.
Return values
-
nlogL is the negative log-likelihood.
-
avar is the inverse of the Fisher information matrix.
(The Fisher information matrix is the second derivative of the negative log
likelihood with respect to the parameter value.)
