Function File: 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.)
