scoreComponent

The function evaluates the formula used to compute the first component of the score function. The
missing elements are imputed with 0.

An implementation for computing Optimal B-Robust Estimators of two-parameter
distribution. The procedure is composed of some equations
that are evaluated alternatively until the solution is reached. Some tools
for analyzing the estimates are included. The most relevant is
covariance matrix computation using a closed formula.
