Abstract:
The Fisher information matrix for a mixture of two Laplace distributions is derived. Numerical tabulations of the matrix and a computer program are provided for practical purposes. The work is motivated by two real–life examples discussed in Hsu (Appl Stat 28:62–72, 1979) and Bhowmick et al. (Biostatistics 7:630–641, 2006).
